Avinash can run with a speed of 8 m s–1 against the frictional force of 10 N, and Kapil can move with a speed of 3 m s–1 against the frictional force of 25 N. Who is more powerful and why?
Power of Avinash Pa = Fa . Wa = 10 x 8 = 80 W
Power of Kapil Pk = Fk . Wk = 25 x 3 = 75 W
So, Avinash is more powerful than kapil.
