A ball released from a height \( h_{0} \) above a horizontal surface rebounds to a height \( h_{1} \) after one bounce. The graph that relates \( h_{0} \) to \( h_{1} \) is shown in figure. 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
(1) \( (0.8)^{3} m g h \)
(2) \( (0.8)^{2} m g h \)
(3) \( 0.8 \mathrm{mg}(\mathrm{h} / 3) \)
(4) \( \left[1-(0.8)^{3}\right] \mathrm{mgh} \)
