1. A 65-kg ice hockey goalie, originally at rest, catches a 0.145-kg hockey puck slapped at him at a velocity of 35 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. A sketch from the animation from Part 1 should look like this. Note the subscripts i and f indicate velocities before and after the collision, respectively. The subscripts p and g represent the puck and the goalie, respectively.
