Answer:
71.66 watt is the power required to move the bag
Option: C
Explanation:
From the given question, Work done is 12900 J (work is the product of force and displacement) in 3 minutes.
We know that, rate of work done is the power.
[tex]\text { Power }=\frac{\text {work}}{\text {time}}[/tex]
Substitute the given values in the above formula to obtain power required to move the bag.
[tex]\text { Power }=\frac{12900 \mathrm{J}}{3 \times 60 \mathrm{s}}[/tex]
[tex]\text { Power }=\frac{12900 \mathrm {J}}{180 \mathrm {s}}[/tex]
[tex]\text { Power }=71.667 \mathrm{Watt}[/tex] (Joule per second is equal to watt )
Therefore the power required to move the bag is 71.66 watt.
