Question

the cable of an electric motor exerts a force of 30 N on a body and pulls it through a distance of 20 m in one minute. what is the power of the motor​

Answer 1

Explanation:

It seems to be pretty simple

Let first to calculate power We calculate the WorkDone by Motor

∆W=force × displacement

i.e. =30×20=600J

Now we calculate the power

Power=Workdone per unit time

P=w/t

P=600/60

power=10J/sec

I hope it helps you...
