how would i solve this?
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 240 N. How much work is done by the rope on the sled in a time interval of 10.0 s?

break the tension of the rope into horizontal and vertical components.

work done=horizontalforce*distance
= horizontal force*velocity*time
