Laws of Motion

A ball of mass 0.15 kg is dropped from a height of 10 m, strikes the ground and rebounds to the same height. The magnitude of the impulse imparted to the ball is ( $g = 10 m/ s^{2}$ ) nearly:

A.0 kg m/s
B.4.2 kg m/s✓
C.2.1 kg m/s
D.1.4 kg m/s

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
