A 70.0 kg ice hockey goalie, originally at rest, has a 0.170 kg hockey puck slapped at him at a velocity of 33.5 m / s. Suppose the goalie and the puck have an elastic collision, and the puck is reflected back in the direction from which it came. What would the final velocities of the goalie and the puck be in this case

    Final velocity of both goalie & puck = 0.018116 m/s

    Explanation:

    M1U1 + M2U2 = (M1+M2) V

    70 x 0 + 0.17 x 33.5 = (70+0.17) V

    V = 0.08116m/s
