Question

A 15-kg cart filled with apples is sitting at the top of a bill that is 21 m high. The apples in the

your cart have a mass of 33 kg. What is the potential energy of the cart and the apples? Round your answer to the nearest tenth

Answer 1

Hi there!

Recall the equation for gravitational potential energy:

`U = mgh`

U = GPE (J)
m = mass (48 kg)
g = acceleration due to gravity (9.8 m/s²)
h = height (21 m)

Plug in the givens and solve.

`U = (15 + 33)(9.8)(21) = \boxed{9878.4 J}`
