    A block B is pushed momentarily along a horizontal surface with an initial velocity v. If \[\mu \] is the coefficient of violling friction between B and the surface, block B will come to rest after a time

    A)  \[\frac{v}{g\mu }\]                        

    B)         \[\frac{g\mu }{v}\]

    C)  \[\frac{g}{v}\]                  

    D)         \[\frac{v}{g}\]

    Correct Answer: A

    Solution :

    For equilibrium position, (v = 0) Force applied = Frictional force \[ma=\mu \,mg\] \[m\left( \frac{v}{t} \right)=\mu mg\]or \[t=\frac{v}{g\mu }.\]
