Dog's Total Energy

CLMECH-MMOULK

A $28 \space kg$ dog is running up a hill at $14 \space m/s$. If the hill is $20 \space m$ high and the dog continues to run at this speed, how much is the dog's total mechanical energy at the top of the hill?

Take that the dog's potential energy is zero at the bottom of the hill.

A

$756$ $J$

B

$294$ $J$

C

$5.5$ $kJ$

D

$8.2$ $kJ$
