Physical Science Homework?
A brick is suspended above the ground on an planet at a height of 6.5 m. It has a mass of 4.5 kg. If the gravitational potential energy is measured to be 350 J, what is the acceleration due to gravity experienced on this planet?

350 = 6.5*4.5*g
g = 350 / (6.5*4.5) = 12.0 m/sec^2

How could you possibly "measure" gravitational potential energy? Normally we measure the force, then multiply by distance to get the work done. but if P = F * d = m*a*d
-> a = P / ( m*d) = 350/(6.5 * 4.5) m/s^2
