1. A 14 N force is applied for 0.33 seconds. Calculate the impulse.
2. A 48 kg object is moving 12 m/s down. It hits the ground and bounces up moving 10 m/s.
A. Which velocity is negative?
B. Calculate the initial momentum of the object.
48kg
10m/s
12m/s
48kg
C. Calculate the final momentum of the object.
D. Remembering that "change of" is always final – initial,
what is the change of momentum of the object?
