What will be maximum speed of a car on a curved road of radius 30 m , If the coefficient of friction between the tyres and the road is 0.4?
`(g=9.8 m//s^(2))`

A

`10.84 m//s`

B

`9.84 m//s`

C

`8.84 m//s`

D

`6.84 m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`V=sqrt(mu rg)`
`=sqrt(0.4xx30xx9.8)=sqrt(12xx9.8)`
`=sqrt(105.6)=10.84 m//s`.
