When serving, a tennis player hits the ball horizontally. With a speed of 29.12 m/s. What minimum height, H (in m) from which the ball must be launched to just clear the 0.90 m high net about L = 17.65 m from the server.
How far from the end of the service box (which is a distance of S = 6.80 m from the net) will the ball land if it just clears the net? Use the positive direction if the ball is good (i.e. lands within the service box). Give your answer in meters.
For how long will the ball be in the air? (s)

As a tennis ball is struck, it departs from the racket
horizontally with a speed of 29.0 m/s. The ball hits the court at a
horizontal distance of 20.3 m from the racket. How far above the
court is the tennis ball when it leaves the racket?

During a tennis match, a player serves the ball at 28.6 m/s,
with the center of the ball leaving the racquet horizontally 2.33 m
above the court surface. The net is 12.0 m away and 0.900 m high.
When the ball reaches the net, (a) what is the distance between the
center of the ball and the top of the net? (b) Suppose that,
instead, the ball is served as before but now it leaves the racquet
at 5.00° below...

A ball is kicked horizontally with 15 m/s initial speed from a
cliff. The ball lands 75 m away from the base of the cliff (R =
75m). What is the height of the cliff? What is the hitting velocity
(the velocity of the ball before it hits the ground)? What is the
total time of flight?

A billiard ball with speed of 3.0 m/s in the positive x
direction hits an identical second billiard ball that is at rest at
the origin. After the collision one of the balls has a momentum
with an angle of -24 degrees respect to the positive x axis. The
direction of the momentum of the second ball in degrees is:

A (field) hockey player is running north at a speed of 8 m⋅s−1.
A ball is coming directly towards her from the north at a speed of
18 m⋅s−1. She swings her stick forward, directly north, at a speed
of 6 m⋅s−1 measured in her own frame of reference. What is the
speed of the ball with respect to the hockey stick?
Relative to the hockey stick, the ball is travelling at ____
m⋅s−1.

A 0.060-kg tennis ball, moving with a speed of 5.20 m/s , has a
head-on collision with a 0.085-kg ball initially moving in the same
direction at a speed of 3.36 m/s . Assume that the collision is
perfectly elastic.
Part A: Determine the speed of the 0.060-kg ball after the
collision.
Part B: Determine the speed of the 0.085-kg ball after the
collision.
