6. A tennis player strikes a tennis ball with her racket when the ball is at the uppermost point of its trajectory as shown. Just after impact, the velocity of the ball is directed at an angle of 15° above the horizontal. If the 125 gram ball is in contact with the racket for 0.02 sec, and the average impulsive force exerted by the racket on the ball is of magnitude of 200 N and directed at an angle 9°...

1. A ping pong ball (ball #1, mass of 2g) is held just above a tennis ball (ball #2, mass of 57g) with their centers vertically aligned. When the balls are released, they fall through a vertical distance of 1.27 meters. a) Prove that each ball is traveling at 5.00 m/s just before it hits the ground. The tennis ball (#2) hits the ground and bounces elastically off of it before the ping pong ball (#1) actually hits #2. Since...
A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m.
part 1 of 3A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m. With what velocity does it hit the ground? The acceleration of gravity is 9.8 m/s2. (Let down be negative.) Answer in units of m/s. part 2 of 3 With what velocity does it leave the ground? Answer in units of m/s. part 3 of 3 If the tennis ball were in contact with the ground for 0.0126 s. find the acceleration given to the...

A tennis ball of mass 57.0 g is held just above a basketball of mass 577 g. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.15 m, as shown in the figure below. (a) Find the magnitude of the downward velocity with which the basketball reaches the ground. (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis...
