A toy car having mass

m = 1.30 kg

collides inelastically with a toy train of mass

M = 3.70 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 = 4.65 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.

Question 6.1b:
A block with mass

M = 5.75 kg

is sliding in the positive x-direction at

Vi = 8.70 m/s

on a frictionless surface when it collides elastically in one dimension with a stationary block with mass

m = 1.75 kg.



Determine the velocities,

Vf

and

vf,

of the objects after the collision.

Vf
= m/s
vf
= m/s
