Question

1

An object has a gravitational potential energy of
41772.5J and has a mass of 1550kg. How high is
it above ground?

Answer 1

h = 2.78 m

Step-by-step explanation:

Potential Energy(PE)

Mass(m)

Gravity(g) which is approximately equal to 10.

Height (h)

PE = mgh

41772.5 = 1500 * 10 * h

41772.5 = 15000h

h = 41772.5/15000

h = 2.78 m
