• If a block of mass m at speed v collides inelastically with ablock of mass M at rest, what is the final velocity of each block?What fraction of the initial energy is lost?
• Two identical circular hockey pucks of radius r travelingtowards each other at the same speed v collide elastically. Theircenters are separated by a vertical distance d, which is less thanr. After the collision, with what angle relative to the initialpath of the pucks will each one travel along?
• Explain the physics of Newton’s Cradle.
