A 50.0-g Super Ball traveling at 30.0 m/s bounces off a brick wall and rebounds at 21.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.05 ms, what is the magnitude of the average acceleration of the ball during this time interval?

A jet plane lands with a speed of 91 m/s and can accelerate at a maximum rate of −5.80 m/s² as it comes to rest. From the instant the plane touches the runway, what is the minimum time needed before it can come to rest?

A tennis player tosses a tennis ball straight up and then catches it after 2.00 s at the same height as the point of release.

(a) what is the acceleration of the ball while it is in flight?

(b) what is the velocity of the ball when it reaches its maximum height?

(c) the initial velocity of the ball and

(d) the maximum height it reaches
