1. A straight line is marked in meters in a field. A student begins at the zero-position mark and ends at the 50-position mark. However, the student did not walk along the straight line. He uses a wheel that has a circumference of 1m and finds that it turns 100 times as he walks. What is his displacement?

2. A ball travels 5m then bounces off of a tennis racket and travels 3m within a total of 3s. What is the magnitude of theaverage velocity of the ball?

3.A ball traveling at 3m/s then bounces off of a tennis racket and returns at 2m/s. If the ball is in contact with the racket for 12ms, what is the magnitude of theaverage acceleration of the ball?

4.A sled on a frictionless surface is given a push that causes the sled to have a constant acceleration of 0.75m/s^2. If the sled has an initial velocity of 2m/s, what displacement does the sled have after 30s?

5. A commercial claims that a car can stop on a dime (17.9mm). If a car is initially traveling at 13.4m/s, what acceleration would the car experience coming to a stop in that short distance?
