Before you start your trip you want to plan it and use the physics you learned in science class to predict various quantities. </p><p>1. A car moving without speeding up or slowing down is said to have what kind of speed?</p><p>2. The speed of any object at any given point in time is an example of:</p><p>3. Taking the total distance divided by the total time is an example of: 4. What kind of speed are you reading when you look at the speedometer of a car at a certain point in time?</p><p>5. What is a rate?</p><p>6. Which of the following is not an example of a rate.</p><p>7. For your ski trip, your family decides to drive at an average speed of 110 km/hr and to figure out the time it will take you to get there what quantity must be given?</p><p>8. From your atlas you figure out that it is 1100 km to the ski slopes so using 110km/hr the total time will be:</p><p>9. If you didn’t have an atlas you could figure out the total distance of the trip if you were given what two quantities?</p><p>10. Given a speed of 11 km/hr and a time of 9.1 hours the total distance of the trip is:</p><p>11. When you arrive in Colorado you want to calculate your average speed to see if you actually traveled at 110 km/hr. Knowing the total distance was actually 1250 km and the trip took 12.2 hours what was your average speed for the trip?</p><p>12. When running the two mile run (800m) you run with at a constant rate and it takes you exactly 2 minutes (120 seconds) to run the race. What was your average speed ? 13. Considering you kept the same speed the entire race, answer the following questions:</p><p> a. Did you have a constant speed during the race? Explain your answer.</p><p> b. Did you have a constant velocity during the entire race? Explain your answer.</p><p>14. If it was possible for you to run at the same rate as in question #12 for 1000 seconds, how far could you run?</p><p>15. How long would it take you to run the 1600 m run if you ran it at the same speed as in question #12?</p><p>16. Instead of running the 1/2 mile run all at a contstant speed, you decide to run the last 100 meters faster. If your speed was 6.0 m/s at the 700 m mark with a time of 110 seconds and your speed was 7.5 m/s at the finish line with a time of 120 s, what was your acceleration rate? (Round to the hundredths place)</p><p>17. During the race, you also had to slow down so you wouldn’t run into a runner a head of you. If your speed was 6.0 m/s at the 50 s mark and you slowed down to 4.0 m/s uniformly until the 60 s mark, what was your acceleration rate? (This is actually a deceleration!) (Round to the hundredths place)</p><p>18. Name two different ways in which you could accelerate during a race.</p><p> a.</p><p> b. 19. Given the graph below, sketch the shape of the Velocity vs. Time graph and Acceleration vs. Time graph. t n e m n e o y i t c t i a a c l r o p e l s l i e e c D V c A</p><p>Time (s) Time Time</p><p>20. What type of motion is the sequence of graphs above? t n e n m o e y i t t c i a a c l r o e p l l s i e e c D V c A</p><p>Time (s) Time Time</p><p>21. What type of motion is the sequence of graphs above?</p>
