A 2 kg object moving with a velocity of +5 m/s collides with a 4 kg object that is initially at rest. After the collision, the 2 kg object moves with a velocity of 1 m/s.
(a) Find the velocity of the 4 kg object after the collision.
(b) Find the energy lost in the collision.
c) What is the coefficient of restitution for this collision?
for a i got 3ml/s
