Two frictionless “hoverpucks” (puck 1 and puck 2) with mass 0.20 kg are travelling on a collision course with a third hoverpuck which is at rest and has mass 0.40 kg. Before they collide, puck 1 has velocity (1.0 m/s) î – (1.0 m/s) ĵ. After the collision they all stick together and have velocity (2.0 m/s) î + (0.5 m/s) ĵ. Friction is negligible.

a) What is the velocity of puck 2 before the collision?

b) What is the total impulse on puck 1 during the collision?

c) If the duration of the collision was 0.15 s what was the average force exerted by puck 3 on puck 1?

d) How much kinetic energy is gained or lost by the three-puck system?
