Energy of Child Descending a Slide

APPH12-K6HIM8

A certain child playing on a frictionless slide possesses $1000\text{ J}$ of potential energy at the top of the slide, relative to the bottom of the slide. She gives herself a push so that she also possesses $400\text{ J}$ of kinetic energy at the beginning of her motion down the slide.

How much kinetic energy does she possess at the bottom of the slide?

A

$400\text{ J}$

B

$600\text{ J}$

C

$1000\text{ J}$

D

$1400\text{ J}$
