Chapter 11, Problem 3AP
A baseball is struck by a bat 46 cm from the axis of rotation when the angular velocity of the bat is 70 rad/s. If the ball is hit at a height of 1.2 m at a 45° angle, will the ball clear a 1.2-m fence 110 m away? (Assume that the initial linear velocity of the ball is the same as the linear velocity of the bat at the point at which it is struck.) (Answer: No, the ball will fall through a height of 1.2 m at a distance of 105.7 m.)

Using the above “mean-speed theorem”, calculate the average velocity of a car with constant acceleration from 0 km/hour (initial speed) to 80 km/hour (final speed) over a 5-minute period of time.
average velocity over 5 minutes = 16 kilometers/hour
average velocity over 5 minutes = 20 kilometers/hour
average velocity over 5 minutes = 24 kilometers/hour
average velocity over 5 minutes = 32 kilometers/hour
average velocity over 5 minutes = 40 kilometers/hour
When Galileo Galilei pushed a ball down an inclined plane, it had an initial velocity (vo) of 4.0 meters per second (time = 0 seconds) and a final velocity (vf) of 10.0 meters per second (time = 2 seconds). How far did the ball travel along the inclined plane in these 2 seconds?
14 meters
20 meters
28 meters
40 meters
84 meters

They decided to measure the amount of frictional force experienced by the model car and the distance it traveled in meters.
