a magnetic crane left a mass 1500 through a vertical height of 40m.calculate the work done in operating the crane

• physics -

W= M*g*H

The mass M is presumably 1500 kg
g = 9.8 m/s^2

Do the multiplication.

Work W will be in Joules with these units

• physics -

F=m*g
=1500*9.8=14700N
w=f*s
=14700*40
=58800J
