Projectile Motion FRQ Name: ______2D Kinematics – HW#4 Date: ______Period: _____ Projectile Motion FRQ Name: _______________________ 2D Kinematics – HW#4 Date: ___________ Period: _____ You have been hired by a football team to use physics to improve their kicking game. Before you can give any recommendations to the coach, you will need to gather some data first. You go out on the field and watch the kicker make kicks starting from ground level on the flat horizontal field. 30° 52 yards During one of these kicks, you measure the angle of the kick to be 30° with respect to the ground and that the football travels a horizontal range of 52 yards. (a) What was the range of the football in meters? (1 yd = 0.9144 meters) (b) Based on this kick, what initial velocity, in meters per second, is the kicker capable of giving to a football? (c) Calculate the maximum possible range, in meters, that the kicker could kick a football. 3 m The picture shows a regulation football field with the goal post. The bottom bar of the goal post is 3 meters above the ground. A field goal must clear this height when it reaches the goal post. Based on the information gathered during practice, you are going to report back to the coach the maximum field goal range of the team’s kicker. This information is extremely valuable to the football coach in order to determine what the team should do on 4th down. If the ball is outside the maximum field goal range of the kicker, then the team will have to punt. However, if they are within the kicker’s range, the team can score more points by kicking a field goal. (d) Based on the kicker’s ideal kick that you calculated in part (c), how much time will it take for the football to reach the goal post? (e) Using the time from part (d), calculate the maximum field goal range of the kicker, in yards. This is the maximum distance the kicker can be away from the goal post and still clear the bottom bar. .

  • An Examination of Decision-Making Biases on Fourth Down in the National Football League
    An Examination of Decision-Making Biases on Fourth Down in The National Football League Weller Ross, B.S. Sport Management Submitted in partial fulfillment of the requirements of the degree of Master of Arts in Applied Health Sciences (Sport Management) Faculty of Applied Health Sciences Brock University St. Catharines, Ontario, Canada c September 2016 Dedication This thesis is dedicated to the loving memory of my uncle, David Ross, who passed away on April 14, 2016. Uncle David contributed to the field of sport management for 45 years, dating back to when he earned his undergraduate degree from the University of Tennessee and his master's degree from Ohio University. He went on to have an extremely impressive career in arena management, which included serving as the president of the International Association of Venue Managers (IAVM) and being accorded the industry's most prestigious honor, the Charles A. McElravy Award, which signifies extraordinary contributions to the field. Most importantly, David was a loving uncle and a great mentor. We love you, Uncle David. You will be missed. Abstract The recent developments in the field of sport analytics have given researchers the tools to exam- ine an increasingly diverse set of topics within the world of sport in ways not previously possible (Alamar, 2013; Fry and Ohlmann, 2012). This study analyzes the decision-making processes of high level coaches under different contexts and then determines whether or not a specific subconscious psychological bias, known as the representativeness heuristic, caused the individual to make the choice they did. Past empirical research has examined people's decisions in different contexts and, from those con- texts, made inferences about how those individuals made their decisions and what errors in their decision-making processes could have led to their suboptimal choices (Kahneman and Tversky, 1979; Kobberling and Wakker, 2005; Tom et al, 2007; Tversky and Kahneman, 1992).

The Buckeyes are taking on Miami (Ohio), the MAC champions, and a team it beat by more than 70 points in 2019. Will they prevail against the outmatched RedHawks, and if so, who will Ohio State be facing off with in the upcoming round? Further than that, what will the entire Round of 32 look like for this virtual tournament? Find all those answers below with a game-by-game breakdown of what the video game consoles churned out. Note: For the full explanation of what this tournament is, how these seeds were selected and the schedule for when upcoming rounds will be released, click here for our introduction to the tournament.

Ohio State jumped out to an early lead, and rode into halftime up 42-10, thanks to five Justin Fields touchdowns – four through the air, one on the ground. Even with the backups in, Ohio State had no issues holding off the RedHawks, and second-string quarterback Chris Chugunov even got in on the fun late, delivering a strike to Binjimen Victor for a 59- yard score with just three minutes to play.

  • NFL Time Management: the Role of Timeouts in End-Game Scenarios
    NFL Time Management The Journal of SPORT, 2015, 4(1), 47-64 © Kent State University NFL Time Management: The Role of Timeouts in End-Game Scenarios Bryan Beasley University of San Francisco Ryan Greenwald University of San Francisco Nola Agha University of San Francisco Abstract Time management is an important part of game strategy in the National Football League (NFL), especially in the second half of a game that could be decided by a field goal. This paper determines the in-game factors that contribute to an NFL offensive team’s total time taken to reach field goal range during the final six minutes of regulation in games that are within three points or less. Using data constructed from 2009-2011 NFL regular season games, we find that neither quarterback rating nor the number of All-Pro players affect the speed at a which a team reaches field goal range. However, counter to conventional wisdom, using an offensive timeout during the final drive of the game extends the time it takes to reach field goal range by 22 seconds. On the other hand, the mere availability of an offensive timeout decreases the time it takes to reach field goal range by 19 seconds. Both of these effects are found in games where the offense is behind by 1, 2, or 3 points, but not in tied games. These findings inform in-game coaching decisions for football head coaches. 47 Beasley, Greenwald & Agha Introduction “It’s about strategically giving your team the best chance to win. That’s really the essence of it.

  • A Causal Estimate of Fourth Down Behavior in the National Football League
    Journal of Sports Analytics 5 (2019) 153–167 153 DOI 10.3233/JSA-190294 IOS Press What was lost? A causal estimate of fourth down behavior in the National Football League Derrick R. Yama and Michael J. Lopezb,∗ aBrown University, RI, USA bSkidmore College, NY, USA Abstract. In part driven by academic research, perception in the sports analytics community asserts that coaches in the National Football League are too conservative on fourth down. Using 13 years of data, we confirm this premise and quantify the unobserved benefit that teams have missed out on by not utilizing a better fourth down strategy. Formally, teams that went for it are paired to those who did not go for it via a nearest neighbor matching algorithm. Within the matched cohort, we estimate the additional number of wins that each NFL team would have added by implementing a basic but more aggressive fourth down strategy. We find that, on average, a better strategy would have been worth roughly an extra 0.4 wins per year for each team. Our results better inform decision-making in a high-stakes environment where standard statistical tools, while informative, have possibly been confounded by extraneous factors. “There’s so much more involved with the game than just sitting there, looking at the numbers and saying, ‘OK, these are my percentages, then I’m going to do it this way,’ because that one time it doesn’t work could cost your team a football game, and that’s the thing a head coach has to live with, not the professor." - Bill Cowher, former head coach of the Pittsburgh Steelers (Garber, 2002) 1.
