Question

A circular track of radius 200m is banked at angle 10° if coeffient of friction between weels and road surface is 0.3 then what is maximum permeable speed?

Answer 1

$\sqrt{rg \frac{u + \tan( \alpha ) }{1 - u \tan( \alpha ) } }$
so answer is

$\sqrt{2000 \times \frac{0.3 + \tan( \binom{\pi}{18} ) }{1 - 0.3 \tan( \binom{\pi}{18} ) } }$
solve it u will get answer
