Question

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

Answer 1

Impulse = integral F dt = change in momentum = final momentum - initial momentum

24 (8) - 24 (13)

24 (-8) - 24 (13)
