    A 0.420 kg ice puck, moving east with a speed of 3.04 m/s, has a head-on collision with a 0.930 kg puck initially at rest. Assuming a perfectly elastic collision, what is the speed of the lighter puck? Use east as the positive axis.

    For perfectly elastic collision

    m1u1= m1v1+m2v2 ----Conservation of momentum
    1/2 m1 u1^2 = 1/ m1 ...

    Solution Summary
