Question
A 70.0-kg ice hockey goalie, originally at rest, catches a 0.150-kg hockey puck slapped at him at a velocity of 35.0 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. What would their final velocities be in this case?
$v_p^ = -34.9 \textrm{ m/s}$
$v_G^ = 0.150 \textrm{ m/s}$
