Question

Question 2 and 5, pl

A racquet ball with mass m = 0.248 kg is moving toward the wall at v = 16.5 m/s and at
an angle of 0 = 31° with respect to the horizontal. The ball makes a perfectly elastic
collision with the solid, frictionless wall and rebounds at the same angle with respect
to the horizontal. The ball is in contact with the wall for t = 0.073 s.
1) What is the magnitude of the initial momentum of the racquet ball?
4.1
kg-m/s Submit
+
2) What is the magnitude of the change in momentum of the racquet ball?
kg-m/s Submit
3) What is the magnitude of the average force the wall exerts on the racquet ball?
96.1
N Submit
4)
Now the racquet ball is moving straight toward the wall at a velocity of vj = 16.5 m/s.
The ball makes an inelastic collision with the solid wall and leaves the wall in the
opposite direction at vf = -10.9 m/s. The ball exerts the same average force on the ball
as before.
What is the magnitude of the change in momentum of the racquet ball?
6.79
kg-m/s Submit
5) What is the time the ball is in contact with the wall?
S Submit
