A toy car having mass
m = 1.45 kg
collides inelastically with a toy train of mass
M = 3.55 kg.
Before the collision, the toy train is moving in the positive x-direction with a velocity of
Vi = 2.35 m/s
and the toy car is also moving in the positive x-direction with a velocity of
vi = 4.80 m/s.
Immediately after the collision, the toy car is observed moving in the positive x-direction with a velocity of
1.90 m/s.
b) Determine the change ΔKE in the total kinetic energy. Assume friction and therotation of the wheels are not important so that they do not affect ΔKE.
