A body of mass m moves with a velocity v on a surface whose friction coefficient is `mu`. If the body covers a distance s, before it comes to rest, then v will be `:`

A block of mass m is at rest on a rough inclined plane, whose friction coefficient is mu. Net force exerted by surface on block is :-

A body of mass m, moving with velocity mu collides elasticity with another body at rest having mass M. If the body of mass M moves with velocity V, then the velocity of the body of mass m after the impact is

A body of mass M moving with velocity V explodes into two equal parts. If one comes to rest and the other body moves with velocity v, what would be the value of v ?

A body of mass M moving with velocity V explodes into two equal parts. If one comes to rest and the other body moves with velocity v, what would be the value of v ?

A body of mass M is kept on a rough horizontal surface (friction coefficient = mu ). A person is trying to pull the body by applying a horizontal force but the body is not moving. The force by the surface on the body is,

A body of mass m is kept on a rough horizontal surface of friction coefficient mu . A force P is applied horizontally , but the body is not moving .Find the net force F exerted by the surface on the body .

A body of mass M is kept on a rough horizontal surface (friction coefficient = mu .). A person is trying to pull the body by applying a horizontal force but the body is not moving. The force by the surface on A is F where
