A) \[60.25{}^\circ \]
B) \[63.90{}^\circ \]
C) \[26.12{}^\circ \]
D) \[30.00{}^\circ \]
Correct Answer: B
Solution :
Angle made by cyclist with vertical is\[\theta \]. Then, \[\tan \,(\theta )=\frac{{{v}^{2}}}{rg}=\frac{{{(20)}^{2}}}{20\times 9.8}=\frac{20}{9.8}\] \[\theta ={{\tan }^{-1}}(2.04)=63.7{}^\circ C.\]You need to login to perform this action.
