Avinash can run with a speed of 8m s

Asked by admin @ in Physics viewed by 299 People

Avinash can run in the speed of 8m/s against the frictional force of 10 newton.And kapil can run with a speed of 3m/s against the frictional force of 25 newton. Who is more powerful and why?

Answered by admin @


Hello Pammita !

Avinash : 

v = 8 m/s 

f = 10 N 

Kapil 

v = 3 m/s 

f = 35 N 

Kapil is more power ful 

see as velocity is constant 

then acceleration will be zero 

And the external force will be zero and only frictional force will work and

which  is more on kapil so he is more strong
