    Q:

    		 A sled on a horizontal plane has a massless rocket attached which provides a force of F in the +x direction for exactly 100 m. The frictional force B is equal to F at velocity V of the sled, and the velocity of the sled remains constant for the full 100 m during which F = B. How much work is done on the sled by the force of friction during the 100 m slide?
    		 

    A

    		 100B

    B

    		 100/B

    C

    		 B/100

    D
