PS1: Speed Velocity and Acceleration You must show all of your work to receive credit for this assignment. Answers must be reported using the correct number of sig figs. 1. In a coordinate system in which the direction to the right is positive, what are the distance and displacement of a person who walks 35.0 meters to the left, 18.0 meters to the right, and then 26.0 meters to the left? 2.Billy drops a ball from a height of 1.00 m. The ball bounces back to a height of 0.8 m, then bounces again to a height of 0.5 m, and bounces once more to a height of 0.2 m. Up is the positive direction. What are the total displacement of the ball and the total distance traveled by the ball? 3. You sit in a car that is moving at an average speed of 86.4 km/h. During the 3.3 s that you glance out the window, how far has the car traveled? 4. A pitcher throws a baseball from the pitcher's mound to home plate in 0.46 s. The distance is 18.4 m. What was the average speed of the baseball? 5. Cassie walked to her friend's house with an average speed of 1.40 m/s. The distance between the houses is 205 m. How long did the trip take her? 6 A marble rolls 5.2 m in 1.8 s. What is the marble's average speed? 7. A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00s. What is its acceleration? 8. A woman backs her car out of her garage with an acceleration of 1.40 m/s². How long does it take her to reach a speed of 2.00 m/s? 9. The driver of a sports car traveling at 10.0 m/s steps down hard on the accelerator for 5.0 s and the velocity increases to 30.0 m/s. What was the average acceleration of the car during the 5.0 s time interval? 10. A girl rolls a basketball across a basketball court. The ball slowly decelerates at a rate of -0.20 m/s2. If the initial velocity was 2.0 m/s and the ball rolled to a stop at 5.0 sec after 12:00 p.m., at what time did she start the ball rolling?
