1. A block of mass m1=1.60 kg initially moving to the right with speed 4.00 m/s on a frictionless horizontal track collides with a spring that is attached to a second mass, m2=2.10 kg that initially is moving to the left with speed 2.50 m/s as shown above. During the collision the spring first compresses and then expands so that both m1 and m2 move off in opposite directions. Because the internal force caused by the spring is conservative, we know that both momentum AND kinetic energy are conserved. Find the final velocity of both masses.

Initially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in Figure P11.40. They are released from rest simultaneously and collide elastically in the trough of the track. If m2 = 4 m1, m1 = 0.045 kg, and h = 0.65 m, what is the velocity of each ball after the collision?
Initially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in Figure P11.40.
