Question

If a stationary cart is struck head-on by a cart with twice mass of the stationary one and a velocity of 5 m/s, what will be the new velocity of the stationary cart if the collision is inelastic?

Show all calculations leading to an answer.

Answer 1

(2m)u = (m+2m)v
v= (2/3)u
= (2/3)(5meters/s)
= 3.33 meters/s

Answer 2

Correct, well-done!
