To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.
The power is the rate at which the energy is delivered. It takes more power
to lift the load faster.
The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),
and the unit of the answer is watts.
