A car of mass 1000 kg moves on a circular track of radius 20 m . If the coefficient of friction is 0.64, then the maximum velocity with which the car can move is

A

22.4 m/s

B

5.6 m/s

C

11.2 m/s

D

6.5 m/s

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(max) = sqrt(mu rg) = sqrt(0.64 xx 20 xx 9.8 ) = 11.2 m//s`
