A 0.450-kg ice puck, moving east with a speed of 5.58 m/s , has a head-on collision with a 0.990-kg puck initially at rest. Assume that the collision is perfectly elastic. Part A What is the speed of the 0.450-kg puck after the collision? Express your answer to three significant figures and include the appropriate units. Part B What is the direction of the velocity of the 0.450-kg puck after the collision? What is the direction of the velocity of the 0.450-kg puck after the collision?
