When the engine is switched off vehicle of mass M is moving on a rough horizontal road eith moment p. If the coefficient of friction between the road and tyres of vehicle is `mu_k`, the distace travelled by the vehicle before it comes to rest is

Options

A. `(p^2)/(2mu_k M^2g)`
B. `(2mu_k M^2G)/(p^2)`
C. `(p^2)/(2mu_(kg))`
D. `(p^2M^2)/(2mu_(kg))`

Explanation

Let,L-Total length of chain
l-Length of the hanging chain
coefficient of friction, `mu=("Hanging length")/("Length")` of chain on the table
`mu=l/(L-l)`
`impliesl= (muL)/(1+mu)`
