V = 100km/hr = 100x (1000/3600) m/s = 27.78 m/s;
E+f = 0.07+0.15 = 0.22;
Now, R = V^2/g (e+f) m/s
= 27.78^2/ (9.81*0.22)
= 357.52 m/s say, 360 m/s.
E+f = 0.07+0.15 = 0.22;
Now, R = V^2/g (e+f) m/s
= 27.78^2/ (9.81*0.22)
= 357.52 m/s say, 360 m/s.

e+f = v^2/127R so putting value of given data,
0.07+0.15=100^2/127R,
R = 10000/127*0.22,
= 357.90,
= 360.
0.07+0.15=100^2/127R,
R = 10000/127*0.22,
= 357.90,
= 360.

Absolute maximum radius?

e+f>= V^2/gR.
=> (g- gravity 9.81).
=> (g- gravity 9.81).
