What would be the maximum speed of a car on a road turn of radius 30 m, if the coefficient of fraction between the types and the road is 0.4 ?
A
`6.84 m//s`
B
`8.84 m//s`
C
`10.84 m//s`
D
`4.84 m//s`
Text Solution
Verified by Experts
The correct Answer is:
C
`v= sqrt( mu mg) = sqrt( 0.4xx30xx9.8)=10.84 m//s `
