Question

A table of mass 10 kg is lifted so that the gravitational potential energy of the table increases by 1470 J. How high is the table lifted? Acceleration due to gravity is g = 9.8 m/s2.

Answer 1

15 meters due to the fact that gravitational potential energy equals mass times gravity times height.

Answer 2

The equation to find height is H=GPE/mg

The GPE is:1470

mass:10

And the acceleration is: 9.8

plug it all in and you get H=1470/10 x 9.8

The answer is 15
