Question

At what height is an object that has a mass of 50kg if its gravitational potential energy is 9800J

Answer 1

Answer:

20m

Explanation:

The equation for gravitational potential energy is:

Ep = mgh

Rearrange,

H = $\frac{Ep}{mg}$

The gravitational field strength for Earth is 9.8 (N/kg)

50×9.8 = 490

9800 ÷ 490 = 20

height = 20m
