If `mu` is the coefficient of friction between the tyres and road then the least stopping distance for a car of mass m moving with velocity v is

A

`v^2//2mug`

B

`v//2mug`

C

`2v//mu^2g`

D

`2v//mug`

Text Solution

Verified by Experts

The correct Answer is:
A
As,` v^2 =u^2 + 2as`
Here, `u = v a=-mug, v = 0, s= ?`
`0=v^2 +2(-mug)simpliess =v^2/(2mug)`
