PhysicsEasysingle choice

A blockBis pushed momentarily along a horizontal surface with an initial velocity v. Ifμis the coefficient of sliding friction betweenBand the surface, blockBwill come to rest after a time

Options:

Answer:
A
Solution:

Block B will come to rest, it force applied to it will vanish due to frictional force acting between block B and surfaceie,

force applied=frictional force

ie,  μ mg=ma

or         μ mg=mvt

or     t=vμ g
