A ball released from a height ho above a horizontal surface rebounds to a height `h_(1)`, after one bounce. The graph that relates `h_(0)` to `h_(1)` is shown Fig. If the ball (of the mass `m`) was dropped from an initial height `h` and made three bounces, the kinetic energy of the ball immediately after the third impact with the surface was
