    Take g= 9.8 m/s^2.

    A 0.5 kg ball moving at 12 m/s collides centrally with a 0.25 kg ball moving in the opposite direction at 18 m/s. If the collision is inelastic and the balls stick together after colliding find:

    1) the common velocity after impact,

    2) the loss in kinetic energy in the collision, and

    3) what forms does the missing energy take?

    1) The common velocity after impact:

    Applying the law of conservation of momentum,
    m1v1 + m2v2 = (m1 + m2)v

    Therefore,
    v = (m1v1 + m2v2)/(m1 + m2)
    = (0.5*12 - 0.25*18)/(0.5 ...

    Solution Summary

    Law of conservation of momentum is applied in the solution.
