Given
Weight of the bricks, W=916N
Height,, h=13.2 m
Time taken, t=28.2s
To find
The power the motor must produce
Explanation
The power is the ratio of work done per unit time
Thus
[tex]\begin{gathered} P=\frac{W\times h}{t} \\ \Rightarrow P=\frac{916\times13.2}{28.2} \\ \Rightarrow P=428.76W \end{gathered}[/tex]
Conclusion
The power produced is 428.76W
