Atoy car having mass m = 1.50 kg collides inelastically with a toy train of mass m = 3.60 kg. before the collision, the toy train is moving in the positive x-direction with a velocity of vi = 2.45 m/s and the toy car is also moving in the positive x-direction with a velocity of vi = 4.75 m/s. immediately after the collision, the toy car is observed moving in the positive x-direction with a velocity of 2.15 m/s.
(a) determine vf, the final velocity of the toy train.
