Avinash With Speed Against Frictional Force Kapil Move With Speed Against Frictional Force

Avinash can run with a speed of 8 ms-1 against the frictional force of 10 N and Kapil can move with … force of 25 N. Who is more…

Answers:

Given, force applied by Avinash = 10 N
Speed of Avinash = 8 ms-1                                               ‘
Power of Avinash = F.v = 10×8 = 80W
Now, force applied by Kapil = 25 N
Speed of Kapil = 3ms-1
Power of Kapil = Fv = 25×3 = 75W
Since, Avinash has more power (80 – 75) = 5 W than Kapil. So, Avinash is more powerful.
