When the engine is switched off a vehicle of mass M is moving on a rough horizontal road with momentum p . If the coefficient of friction between the road and tyres of the vehicle is _k , the distance travelled by the vehicle before it comes to rest is
Options
- Ap^2 2 _k M^2 g
- B2 _k M^2 g p^2
- Cp^2 2 _k g
- Dp^2 M^2 2 _k g
Correct answer
A. p^2 2 _k M^2 g
Step-by-step solution
We have, _k m g s= p^2 2 M or s= p^2 2 M^2 _k g
