A 2.0 kg object moving with a velocity of +8.0 m/s collides with a 8.0 kg object that is initially at rest. After the collision, the 2.0 kg object moves with a velocity of -1.0 m/s.
(a) Find the velocity of the 8.0 kg object after the collision.
m/s
(b) Find the energy lost in the collision.
J
(c) What is the coefficient of restitution for this collision?
