Before a collision, a 24 kg object is moving at +13 m/s. Find the impulse that acted on the object if, after the collision, it moved at the following velocities.
(a) +8.0 m/s
(b) 8.0 m/s

Impulse = integral F dt = change in momentum = final momentum  initial momentum
24 (8)  24 (13)
24 (8)  24 (13)
