Question

Force and Laws of Motion
all of mass 0.15 kg strikes a smooth wall with a speed of 10 m s-1 and rebounds back with the same
ed along the same straight line. What is the change in momentum of the ball?
Ans: -3.0 kg m s']​

Answer 1

Answer:

-3kg m/s

Explanation:

Change in momentum = final momentum - initial momentum

momentum = 0.15×10 = 1.5

changw in momentum = -1.5 - 1.5 = -3 kg m/s
