A ball of mass 8 kg moving with a speed of 2m/s and rebounds with the same speed.Determine the impulse experienced by the ball.

(a)20.0kg/m (b)10.0kg/m (c)0.01kg/m (d)1.3kg/m

impulse = change of momentum

= 8 (2 - -2) = 8*4 = 32 kg m/s

none of above, even units are no impulse which is force times time
- Newton seconds or momentum change kg m/s
