A book is pushed off the edge of a table. At what point during the fall will the potential and kinetic energy be equal? A. 1/4 of the way down B. 1/2 of the way down C. 3/4 of the way down D. right before it hits the ground

Respuesta :

The point during the fall will the potential and kinetic energy be equal is B. 1/2 of the way down.

How to illustrate the information?

It should be noted that the point when the potential and kinetic energy be equal will be at the midpoint of the initial height.

Therefore, the object possesses potential energy when at rest and then kinetic energy when in motion.

When KE = PE

We can deduce that KE+PE = MGH and  PE+ PE = MGH

This implies that MGH + MGH= 2MGH and  2H = H

Therefore, the point during the fall will the potential and kinetic energy be equal is B. 1/2 of the way down.
