Question

An object is dropped from a height of 23 m. At what height will it’s kinetic energy and its potential energy be equal

Answer 1

Step-by-step explanation:

Potential enrgy is m g h

Kinetic enrgy is 1/2 mv^2 as the book falls PE is converted to KE

at the 1/2 way point 1/2 of the PE has been converted to KE ...at this point they are equal

11.5 m
