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 (see the figure below). The total weight of the sled is  470 N. The tension in the rope is  270 N. How much work is done by the rope on the sled in a time interval of  20.0 s?
