A car is travelling at 30 km/ h in a circle of radius 60 m what is the minimum value of `mu_(s)` for the car to make the turn without skidding

Text Solution

Verified by Experts

Given `v=(30 km)/(h ) = (30 xx 1000)/(3600)`
`=(m)/(9s ) = (25)/(3) m//s`
`r=60 m`
`g=10`
formula Minimum value of
`mu_(s) = (v^(2))/( r g)`
`:. , mu_(s) = (25)/(3) xx (25)/(3) xx (1)/(60 xx 10)`
`mu_(s) = 0.115`
