Q. A 50g Super Ball travelling at 26.0 m/s bounces off a brick wall and rebounds at 19m/s. A high-speed camera records this event. If the ball is in contact with wall for 3.50ms, what is the magnitude of the average acceleration of the ball during this time interval? (Note: 1 ms = 10-3 s.)

Q. At one instant a bicyclist is 53m due east of a park's flagpole, going due south with a speed of 12m/s. Then 37s later, the cyclist is 53m due north of the flagpole, going due east with a speed of 12m/s. For the cyclist in this 37s interval, what are (a) magnitude and (b) direction of the displacement, the (c) magnitude and (d) direction of the average velocity, and the (e) magnitude and (f) direction of the average acceleration?
