Energy and its Conservation

Energy and its Conservation problem 46

A body of mass resting on a horizontal rough surface is pushed so that it begins to move in a horizontal direction at a speed of . The coefficient of friction between the body and the surface is .

  • What is the initial kinetic energy of the body?

  • At what distance does the body stop?

  • How does the kinetic energy change if the final velocity is one-third of the initial velocity?
