Question

one car of mass 15.0kg is moving 5.00m/s to the right on a frictionless track and collides with a cart of mass 3.00kg. the final velocity of the carts that become stuck together after the collision is 1.50m/s to the right. find the velocity of the second cart before the collision.

M1*V1 + M2*V2 = M1*V + M2*V
15*5 + 3*V2 = 15*1.5 + 3*1.5
3V2 = 27 - 75 = -48
V2 = -16 m/s = 16 m/s to the left.
