  • question_answer
    A motorcycle is travelling on a curved track of radius 500m. If the coefficient of friction between road and tyres is 0.5, the speed avoiding skidding will be                       [MH CET (Med.) 2001]

    A)             50 m/s

    B)             75 m/s

    C)             25 m/s

    D)             35 m/s

    Correct Answer: A

    Solution :

                    \[v=\sqrt{\mu rg}=\sqrt{0.5\times 500\times 10}=50\ m/s\]
