Explanation:
When a boy throws a ball and accidentally breaks a window, the momentum of the ball and all the pieces of glass taken together after the collision is THE SAME as the momentum of the ball before the collision
Answer:
6m/s
Explanation:
momentum = mass × change in velocity
∆p =m(v)
24 = 4(v)
V =>24/4 = 6m/s
