In the overhead view of the figure, a 450 g ball with a speed v of 6.2 m/s strikes a wall at an angle e of 24° and then rebounds with the same speed and angle. It is in contact with the wall for 7.1 ms. In unit-vector notation, what are (aj the impulse on the ball from the wall and (b) the average force on the wall from the ball?
