B) Use an inclined plane of length 2 m.

C) Use an inclined plane of length 10 m.

D) Use an inclined plane of length 16 m.

    Work = force * distance.

    We must produce twice as much energy as we are lifting the weight twice as high.

    But we are not increasing the force so we must increase the length of the ramp (distance) instead.

    The new length will be twice as great as the previous length.

    So 8 metres is required.

    25 kg * 8 m = work = 100 kg * 2 m
