Question

A car is moving along a straight horizontal road with a speed `v_(0)` . If the coefficient of friction between the tyres and the road is `mu` , the shortest distance in which the car can be stopped is
A. `(V_(0)^(2))/(2mug)`
B. `(V_(0)^(2))/(mug)`
C. `((V_(0))/(mug))^(2)`
D. `(2V_(0)^(2))/(mug)`

Answer 1

Correct Answer - A
`O^(2)-V_(0)^(2)=2(-mug)xxs`
`s=(V_(0)^(2))/(2mug)`
