Question

How high would a 20 kg mass have to be raised to have a gravitational potential energy of 1,000 J?

Answer 1

We can solve using the formula for gravitational potential energy(GPE = mgh)

M(mass) = 20 kg
g(gravitational constant) = 9.8 m/s^2
GPE = 1000

1000 = 20*9.8*h
1000 = 196h
h = 5.102 meters
