1) the same as at the top,
2) one quarter the amount at the top,
3) one half the amount at the top,
4) more than one-half the amount at the top,
and compared to his kinetic energy when meeting the net, his kinetic energy at the half-way point is
5) one half.
6) the same as his potential energy at the half-way point.
7) both of these
8) neither of these
