1) A toy car having mass m = 1.35 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 V_i = 2.10 m/s and the toy car is also moving in the positive x-direction with a velocity of v_i = 4.70 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 V_f, 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.

____J

Question 6.1b:
2) A block with mass M = 6.10 kg is sliding in the positive x-direction at V_i = 8.90 m/s on a frictionless surface when it collides elastically in one dimension with a stationary block with mass m = 1.40 kg.

Determine the velocities, V_fand V_f of the objects after the collision.

V_f= ___m/s

V_f=___m/s
