A car (treat it as particle) of mas 'm' is accelerating on a level smooth roud under the action of single force F. The power dellvered to the car is constant and equal to P. If the velocity of the car at an instant is v, then after traveclling how much distance it becomes double ?

Options

A. `(7mv^(3))/(3p)`
B. `(4mv^(3))/(3p)`
C. `(mv^(3))/(P)`
D. `(18mv^(3))/(7P)`

Explanation

`P=m(vdv)/(ds).v`
`underset(v)overset(2_(v))intmv^(2)dv=underset(o)overset(r)intPds`
`s=(7mv^(3))/(3P)`
