1. A Basketball player stands at center court. She runs 19 m to the right in 5 s, then she turns around and runs 24 m to the left in the next 5 s. a. What distance did she travel during the last 5 s?
b. What was the average speed for the entire 10 s?
c. What is the displacement during the last 5s?
d . What is the total displacement?
e. What was the average velocity for the entire trip?

F. The player then returns to the center of the court in some amount of time. What was her velocity for the entire trip? How can you know her velocity if you don’t know exactly how much time she was moving?
3. You see a car moving at a constant velocity. You see the car move 21m in the first 4 seconds.
What is the velocity of the car?
How long will it take the car to reach a sign that is 112 m away?
4. A rocket’s speed increases from 10 m/s to 280 m/s in 9 seconds.
Use the formula the acceleration to find the acceleration of this rocket.
What is the rocket’s velocity after 12 seconds if the acceleration stays the same?
5. A racecar accelerates from a speed of 106 m/s to a complete stop in 6.8 seconds. What is its average acceleration for the car?
6. A car starting from rest accelerates at a rate of 4.0 m/s/s for 7 seconds
What is its final velocity at the end of 10.0 seconds?
How far did it travel?
7. The motion diagram shows the motion of an object during the first 4 seconds of its motion.
Write a motion claim supported by evidence about the motion of the object. Include information about the type of motion and direction.
Is the velocity of the object positive or negative? Justify your choice.
Is the acceleration be positive or negative? Justify your choice.
8. The tables below give data about a car during 4 seconds of its motion.
Make an X vs. T graph with labeled axes for the data provided.
What direction is the car moving, + or -? How do you know?
Is the Car’s velocity positive or negative? How do you know?
Looking at your graph in part a, Does the car speed up, slow down, or move with constant speed? Explain how the shape of the graph indicates the motion of the car.
Calculate the average velocity of the car between 0 and 4 seconds.

9. A car driving at 45 m/s applies the brakes and slows with and acceleration of at a rate of -7.0 m/s/s for 5 seconds.
What is its final speed of the car after 5 second?
How far did it travel? (must show a graph or a formula) ]
