A ball of mass.62 kg has an initial velocity of 7 m/s and moves at an angle of 32° above the +x-direction. The ball hits a vertical wall and bounces off so that it is moving 32° above the -x-direction with the same speed. (a) What is the magnitude of the impulse delivered by the wall? Number (b) What is the direction of the impulse delivered by the wall?
