1.7.4 Power

Four different motors are used to lift loads of different masses vertically through the same height.

\begin{array}{|c|c|c|}\hline \text{Motor} & \text{Mass of load / kg} & \text{Time taken / s} \\ \hline \text{P} & 150 & 15 \\ \hline \text{Q} & 150 & 30 \\ \hline \text{R} & 300 & 15 \\ \hline \text{S} & 300 & 30 \\ \hline \end{array}

Which motor has the greatest power output?
