Question
A block B is pushed momentarily along a horizontal surface with an initial velocity v. If is the coefficient of vlicling friction between B and the surface, block B will come to rest after a time
Solution
A.
Block will come to rest, if force applied on it. It will vanish due to frictional force acting between block Band surface, i.e.,
Force applied = Frictional force
⇒ μ mg = ma
⇒ μ mg =
⇒ t =
