1.	A car is travelling at 30 km/ h in acircle of radius 60 m what is the minimum value of mu_(s)for the car to make the turn without skidding
Answer» Solution :Given `v=(30 km)/(H ) = (30 xx 1000)/(3600)` `=(m)/(9s ) = (25)/(3) m//s` `r=60 m` `g=10` formulaMinimumvalue of `mu_(s)= (v^(2))/( r g)` `:., mu_(s)= (25)/(3) xx (25)/(3) xx (1)/(60 xx 10)` `mu_(s) = 0.115`
