Question
A person throws a ball up into the air and the ball falls back toward Earth at which point would the kinetic energy be the lowest A when the ball is at its highest point B at a point when the ball is still rising C at a point before the ball hits the ground D when the ball leaves the person hand

The kinetic energy of the ball is lowest at the point when it stops rising and starts to fall back down, which occurs at its highest point. Therefore, the answer is:
**A) when the ball is at its highest point**
At this point, the ball's velocity is zero, and hence its kinetic energy is also zero. At all other points (while it is still rising, before it hits the ground, or just after leaving the person's hand), the ball has some velocity, and thus it has kinetic energy.
**A) when the ball is at its highest point**
At this point, the ball's velocity is zero, and hence its kinetic energy is also zero. At all other points (while it is still rising, before it hits the ground, or just after leaving the person's hand), the ball has some velocity, and thus it has kinetic energy.
