Question

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.

Answer #1

A tennis ball is struck and departs from the racket horizontally
with a speed of 28.9 m/s. The ball hits the court at a horizontal
distance of 18.8 m from the racket. How far above the court is the
tennis ball when it leaves the racket?

A tennis player swings her 1000 g racket with a speed of 10 m/s
. She hits a 60 g tennis ball that was approaching her at a speed
of 19 m/s . The ball rebounds at 35 m/s .
Part A 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. Express your answer in
meters per second. v = nothing...

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.

The tennis ball has a horizontal speed of 15 m/s when it is
struck by the racket. If it then travels away at an angle of 25°
from the horizontal and reaches a maximum altitude of 10 m,
measured from the height of the racket, determine the magnitude of
the net impulse of the racket on the ball. The ball has a mass of
180 g. Neglect the weight of the ball during the time the racket
strikes the ball

A highspeed golf ball hit a club. The club was in contact with a
ball, initially at rest, for about 0.0037 s. If the ball has a mass
of 55 g and leaves the head of the club with a speed of 2.4 ✕
102 ft/s, find the average force (in kN) exerted on the
ball by the club.

A soccer player kicks a soccer ball of mass 0.50 kg that is
initially at rest. The player's foot is in contact with the ball
for 1.8 10-3 s. The force of the kick is given by the following
formula for 0 t 1.8 10-3 s, where t is in seconds. F(t) = [(7.2
106)t - (2.2 109)t2] N (a) Find the magnitude of the impulse
imparted to the ball. Incorrect: Your answer is incorrect. Ns (b)
Find the magnitude...

After falling from rest from a height of 33 m, a 0.60-kg ball
rebounds upward, reaching a height of 23 m. If the contact between
ball and ground lasted 2.3 ms, what average force was exerted on
the ball? (Enter the magnitude.)
