A) \[~10\,m{{s}^{-1}}\]
B) \[~20\,m{{s}^{-1}}\]
C) \[~30\,m{{s}^{-1}}\]
D) \[~5\,m{{s}^{-1}}\]
Correct Answer: C
Solution :
We know banking angle is related with velocity and radius of the curve as \[\tan \theta =\frac{{{v}^{2}}}{rg}\] \[\Rightarrow \] \[v=\sqrt{900\times 10\times \tan {{45}^{o}}}=30\,m/\sec \]You need to login to perform this action.
