A car of mass 800 kg moves on a circular track of radius 40 m . If the coefficient of friction is 0.5, then maximum velocity with which the car can move is

A

7 m/s

B

14 m/s

C

8 m/s

D

12 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`V_("max") = sqrt(murg) = sqrt(0.5 xx 40 xx 9.8) =14 m//s`
