A trolley is pushed along a road with a force of 400 N through a distance of 60 m in 1 minute. Calculate the power developed.

Here given, Applied force $F=400\ N$

displacement $d=60\ m$

Time taken $t=1\ minute=60\ s$

So, the work done on trolley $=Force\times displacement$

$=400\ N\times 60\ m$

$=24000\ Joule$

Therefore, power$=\frac{work\ done}{time}$

$=\frac{24000\ Joule}{60\ s}$

$=400\ Watt$

Thus, the power developed on pushing the trolley is $400\ Watt$.
