Here,
Coefficient of statistic friction (c) =0.60
Velocity (v)= 110km/hr =30.5m/s
We know,
F = (mv2)/r
Or, ma =mv²/r [F=ma]
Or, a=v²/r [mass is same]
Or, cg =v²/r [acceleration =coefficient of static friction acceleration due to gravity]
Or, 0.6010 =(30.5)²/r
Or, r= 155.041 m.
Therefore the minimum radius is 155.041m.
