A pendulum with a mass M swings and picks up a piece of clay of mass m at the bottom of its swing.
A)It rises to the same height after the collision as before.
B)The total mechanical energy of the system is unchanged by the collision.
C)If M = m,then the height it reaches after the collision is half that before the collision.
D)If M = m,then the height it reaches after the collision is 1/4 that before the collision.
E)If M = m,then it rises to twice the height it had before the collision.
