A 1.0 kg ball is bounced high in the air. What is its total kinetic energy when it reaches its highest point?
a
100.0 joules
b
30.0 joules
c
0 joules
d
50.0 joules
e
40.5 joule
The total kinetic energy of the ball at its highest point is 0 joules because the ball has come to a stop at the top of its trajectory. This is when its kinetic energy is at its lowest point and is converted entirely into potential energy. The correct answer is:
c
0 joules
