A steel mass is raised by a suspension line connected to a electric motor and allowed to fall freely under gravity. It then hits the steel column and pushed it into the ground. The falling steel mass has a mass of 200 kg and falls a distance of 6.0m Take g = 10N kg^-1.
Calculate the gravitational potential energy gained by the steel mass each time it is raised. (full working and explanation pls)
