Question

kinetic and potential energy quick check
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? (1 point)
o when the ball leaves the persons hand
o at a point when the ball is still rising
o at a point before the ball hits the ground
o when the ball is at its highest point

Explanation:

Kinetic energy \(K = \frac{1}{2}mv^{2}\), where \(m\) is mass and \(v\) is velocity. When the ball is at its highest point, its vertical velocity \(v = 0\) (momentarily stops moving upward before falling). Since \(K\propto v^{2}\), kinetic energy is lowest here.

Answer:

when the ball is at its highest point
