A 57 g tennis ball strikes hits a wall at 12 m/s at an angle of 25° relative to the normal line perpendicular to the wall, and rebounds with the same speed. Find the magnitude of the impulse delivered by the wall.

(II) A tennis ball of mass $m=0.060 \mathrm{kg}$ and speed $v=25 \mathrm{m} / \mathrm{s}$ strikes a wall at a $45^{\circ}$ angle and rebounds with the same speed and rebounds with the same speed at $45^{\circ}$ (Fig. $7-32 )$ . What is the impulse (magnitude and direction) given to the ball?
1. A tennis ball of mass m = 0.060 kg and speed v = 28 m/s strikes a wall at a 45° angle and rebounds with the same speed at 45°. What is the impulse (magnitude and direction) given to the ball?
