Question
(ans: A)
18. A 3.5 kg ball is moving at an initial velocity of 4.0 m/s due east when it collides with a
5.0 kg moving at 1.8 m/s due north. The balls stick together after the collision.
a) Create a vector diagram illustrating the law of Conservation of Momentum.
b) Determine their common final velocity. (ans: 1.96 m/s 32.7° N of E)
c) Calculate the impulse acting on the 3.5 kg ball during the collision. (ans: 9.0
Ns 24.3° N of W)
