A 75.0 kg ice hockey goalie, originally at rest, catches a 0.150kg hockey puck slapped at him at a velocity of 18.0 m/s. Supposethe goalie and the ice puck have an elastic collision and the puckis reflected back in the direction from which it came. What wouldtheir final velocities (in m/s) be in this case? (Assume theoriginal direction of the ice puck toward the goalie is in thepositive direction. Indicate the direction with the sign of youranswer.)
puck ____ m/s
goalie ____ m/s
