Given that,
Mass of a box, m = 11 kg
It is lifted to a height of 6 m
Time, t = 3s
To find,
The power experienced by the Peter.
Solution,
Power = rate of doing work
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{11\times 9.8\times 6}{3}\\\\P=215.6\ W[/tex]
So, the power experienced by the Peter is 215.6 Watts.
