Energy and its Conservation

Energy and its Conservation problem 47

A body of mass is at rest on a horizontal rough surface. A constant force of , parallel to the surface begins to act on the body. If the coefficient of friction between the body and the surface is ,

  • how much work does the force do when moving the body through a distance of ?

  • how much work does the frictional force do on this movement?

  • what is the final velocity of the body?
