  1. acceleration

Calculate the following. SHOW ALL WORK INCLUDING UNITS IN THE SET-UP AND ANSWER.

  1. Calculate the speed of a train if it covered 200 miles in 100 minutes.
  1. Mr. Flowers can run 10 miles in 1.2 hours. Calculate his speed.
  1. Jason rode his skateboard at a speed of 12 miles per hour. How far did he ride in 4 hours?
  1. You drive 2 miles in 20 minutes because you are in heavy traffic. Then, traffic lightens up and you drive 6 miles in 4 minutes. What is your average speed?
  1. A bus is traveling east on the freeway towards Reno. It is traveling at 60 miles per hour. What is the bus’ velocity?
  1. A car advertisement states that a certain car can accelerate from rest to 65 km/h in 9 seconds. Find the car’s average acceleration.
  1. You and a friend are driving down the freeway at 60 miles per hour when the traffic in front of you suddenly slows down. You put on your brakes but it takes you 5 seconds to slow downto 25 miles per hour . What is your acceleration?
  1. Jeremy ran for 50 s at an average speed of 9 m/s. How far did he run?

Has velocity changed? If there is no change in velocity, write – no change. If there is a change in velocity explain what has changed.

  1. A kid riding his skateboard has to stop for the stoplight to change.
  1. A ferris wheel is turning.
  1. A car gets off the freeway and has to slow down to turn onto a street.
  1. Driving 32 mi/hr on a straight road.

Identify the reference point(s) in each example:

  1. Sarah lives 30 miles northeast of the mall.
  1. The gym is 6 blocks north and 3 blocks west of my house.

  1. What is the slope of the line?
  1. What type of motion is the graph showing?
  1. Is the line linear? Why or why not?
  1. Calculate the slope of a line that passes through the following points:

(2,10), (3, 30), (4,50), (5,75)

  1. Is the slope of the line in question 38 the same for the whole line?
  1. Describe the type of motion that line is showing.

Use the following electricity usage tables to answer the questions:

month / kW used
PERSON A
November / 3458
December / 1266
January / 3408
February / 2572
  1. Calculate the rate of how many kilowatts of electricity were used on average over the 4 months.
  1. Use the average electricity used rate you found above to calculate an average electricity used for an entire year.

month / kW used
PERSON B
November / 285
December / 872
January / 1278
February / 598
  1. Calculate the rate of how many kilowatts of electricity were used on average over the 4 months.
  1. Use the average electricity used rate you found above to calculate an average electricity used for an entire year.

Below are available rate plans. Each plan allows a certain amount of kilowatts to be used each month for a certain price. Each plan also has a price for kW used over the plan limit. The overages can be purchased in blocks of 100kW for $1.00..

Price / Maximum kW per month / Overage charge
Plan 1 / $5.00 / 500 kW / $1.00 per 100kW
Plan 2 / $15.00 / 2000 kW / $1.00 per 100kW
Plan 3 / $30.00 / 5000 kW / $1.00 per 100kW
  1. Use the average minutes used rate to determine the most affordable rate for Person A. The plan you choose should be the cheapest option based on your average minutes used rate.
  1. Explain why that is the best rate. You must use evidence to support your explanation.
  1. Use the average minutes used rate to determine the most affordable rate for Person B. The plan you choose should be the cheapest option based on your average minutes used rate.
  1. Explain why that is the best rate. You must use evidence to support your explanation.
