You are using an electric forklift to load a large truck with computer boxes, as shown in the figure below. In doing this task,
chemical energy stored in the battery is changed into electrical
energy. This electrical energy is then changed by the motor into
mechanical energy to lift the boxes and move the forklift. Some
of the energy is also changed into heat.
Suppose the motor does not have enough force to carry the pallet
of boxes up the ramp. How could the ramp be changed, if at all,
so the forklift could perform the job?
