Power required to raise 1 ton per meter per minute

[Inventor]

I require information on the power required to raise each ton (1000 kg) per meter per minute and the fomula for working this out. To determine the cost of doing this work a kWh figure would be appreciated.

In this case, the energy you supply is converted into potential energy.

Therefore, power = dU/dt where U is the potential energy

Find the function of U with respect to t and differentiate.
