(II) A grocery art with mass of 18 kg is pushed at constant speed along an aisle by a force F = 12 N. The applied force acts at a 20-degree angle to the horizontal. Find the work done by each of the forces on the cart if the aisle is 15 m long.

Please help me solve step by step.

  • physics -

    I tried to solve it.
    No work done by gravity
    No work done by normal
    169.14 J by applied force
    -169.14J by the friction force

    are those correct?

  • physics -

    correct.
