Question

What is the magnitude of the impulse given to the ball?

What is the direction of the impulse given to the ball? (upward, downward, to the left, or to the right)

A tennis ball of mass m = v 24 m/s strikes a wall at a 45° angle and rebounds with the same speed at 45. (Figure 1) 0.060 kg and speed Figure 1 of 1 45

Answer 1

0.060 ka mass of ball = Sbeed = 24 misec - initial momentum = 0.060 X 84 Co845 - 1018 kg-m sec

final momenturn = 0.060x1-24 Sin45) 2-1.018 SEC impulze = change in momentum = -1.018 - 1.018 = -2.036 kg-on see indicate that direction is opposite Negative sign

What we have assumed so the direction given to ball of the will lel impelse on to the left »
