Question

A tennis player swings her 1000 g racket with a speed of 8.0 m/s . She hits a 60 g tennis ball that was approaching her at a speed of 21 m/s . The ball rebounds at 37 m/s .

1. How fast is her racket moving immediately after the impact? You can ignore the interaction of the racket with her hand for the brief duration of the collision.

2.If the tennis ball and racket are in contact for 8.0 ms , what is the average force that the racket exerts on the ball?

Answer #1

1) The ball rebounds with a velocity of v = 7.04m/s

2) Average force exerted by the racket on the ball is F = 120 N.

Calculations are attached below,

A tennis player swings her 1000 g racket with a speed of 12.0
m/s . She hits a 60 g tennis ball that was approaching her at a
speed of 18.0 m/s . The ball rebounds at 45.0 m/s .

A) A 1500 kg weather rocket accelerates upward at
10m/s2. It explodes 1.7 s after liftoff and breaks into two
fragments, one twice as massive as the other. Photos reveal that
the lighter fragment traveled straight up and reached a maximum
height of 520 m .What was the speed of the heavier
fragment just after the explosion?
B) A tennis player swings her 1000 g racket with a speed
of 9.0 m/s . She hits a 60 g tennis ball...

A baseball player swings his 1kg bat at 10m/s as he hits a 60g
baseball that is coming at him at 20m/s. The ball bounces of his
racket at 38m/s.
(a) Draw a before/after picture showing
velocities/directions.
(b) How fast is his bat moving after the collision? In what
direction? If the bat and ball are in contact for only 10ms, what
is the average force on the ball during the collision?

A 71 kg soccer player jumps vertically upwards and heads the
0.45 kg ball as it is descending vertically with a speed of 27 m/s.
If the player was moving upward with a speed of 4.0 m/s just before
impact, what will be the speed of the ball immediately after the
collision if the ball rebounds vertically upwards and the collision
is elastic?

(a) If the player was moving upward with a speed of 4.0 m/s just
before impact, what will be the speed of the ball immediately after
the collision if the ball rebounds vertically upwards and the
collision is elastic?

A tennis ball of mass 60.9 g is Struck from rest with a racket.
The contact time of the ball on the racket is 9.2 ms and the ball
leaves the racket with a velocity of 35 m / s. Calculate the
average force exerted by a racket on a ball. Give an answer to one
decimal place. Remember add unit N after the numerical value.

In tennis, the speed of the ball can reach 60 m/s in a fast
service. How fast must the tennis racket be swung to reach that
speed? Assume the mass of the racket is much larger than the mass
of the ball.
