A solid ball and a box both have the same mass, and both move along the same horizontal surface.
The ball rolls without slipping and the box slides without rotating The surface has nonnegligible
friction. At one instant, the linear speed of both objects is the same. Which statement about the total
kinetic energy of each object is correct?
A The total kinetic energy of both objects is the same.
B The total kinetic energy of the box is larger than the total kinetic energy of the ball.
C A comparison of the total kinetic energy requires knowledge of the relative size of each object.
D A comparison of the total kinetic energy requires knowledge of the friction force.
E The total kinetic energy of the ball is larger than the total kinetic energy of the box.
