HALLIDAY SOLUTIONS - CHAPTER 9 PROBLEM 38 - Fundamentals of Physics 10th

In the overhead view of Fig. 9-54, a 300 g ball with a speed v of 6.0 m/s strikes a wall at an angle u of 30 and then rebounds with the same speed and angle. It is in contact with the wall for 10 ms. In unit vector notation, what are (a) the impulse on the ball from the wall and (b) the average force on the wall from the ball?
