Question

A ball hits a wall at a 45 degree angle at 10.0 m/s and recoils at a 45 degree angle at 10.0 m/s as shown above:






a) If the mass of the ball is 10.0 kg, what is the change in momentum of the ball?
(Hint: do the x and y parts of the problem separately) Ignore gravitational forces in this problem. Include the direction of the change in momentum.





b) What is the impulse that the ball applies to the wall? Include the direction of
the impulse.




c) If the average force exerted by the ball is 10.0 N how long is the ball in contact with the wall?
