A block of mass m is pulled along a horizontal surface by applying a force at an angle theta, with the horizontal. If the block k travels with a uniform velocity and has a displacement d and the coefficient of friction is mu. Then find the workdone by the applied force?

1.	A block of mass m is pulled along a horizontal surface by applying a force at an angle theta, with the horizontal. If the block k travels with a uniform velocity and has a displacement d and the coefficient of friction is mu. Then find the workdone by the applied force?
Answer» `(MU mgd)/((cos theta+mu SIN theta))` `(mu m GD cos theta)/((cos theta+mu sin theta))` `(mu mg d sin theta)/((cos theta+mu sin theta))` `(mu mg d cos theta)/((cos theta+mu sin theta))` Answer :B
