    I need help on total work.....

    2. [GRR1 6.P.002.] A sled is dragged along a horizontal path at a constant speed of 1.5 m/s by a rope that is inclined at an angle of 30.0° with respect to the horizontal (the figure below). The total weight of the sled is 470 N. The tension in the rope is 230 N. How much work is done by the rope on the sled in a time interval of 15.0 s?
    I need the answer in kJ

    What have you done so far ?
    Show us your calculations.

    What's the formula you apply in order to calculate the work ? What two quantities do you need to know in order to be able to apply this formula.

    HINT one of the quantities has been given, you need to calculate the other one yourself.
