Avinash can run at a speed of 8 ms-1 against the frictional force of 10 N, and Kapil can move at a speed of 3 ms-1 against the frictional force of 25 N. Who is more powerful and why?

Power of Avinash PA = F A .v A = 10 x 8 = 80 W

Power of Kapil PK . FK . vK = 25 x 3 = 75 W

So, Avinash is more powerful than Kapil.
