Question

A toy car having mass

m = 1.20 kg

collides inelastically with a toy train of mass

M = 3.90 kg.

Before the collision, the toy train is moving in the positive x-direction with a velocity of

Vi = 2.30 m/s

and the toy car is also moving in the positive x-direction with a velocity of

vi = 4.90 m/s.

Immediately after the collision, the toy car is observed moving in the positive x-direction with a velocity of

2.05 m/s.
(a) Determine
Vf,
the final velocity of the toy train.
m/s

(b) Determine the change
ΔKE
in the total kinetic energy. Assume friction and the rotation of the wheels are not important so that they do not affect
ΔKE.
