Suppose a box on a frictionless ramp is being pulled by a rope with a tension of 350 N making an angle of 50° to the horizontal ground. If the angle of incline of the ramp is 20°, and the box is pulled 5 m, determine the amount of work done. Hint: Draw a diagram and use vectors to represent the situation.

the tension is at 50  20 = 30 degrees to the direction of motion up the ramp.
Therefore the component of force in the direction of motion is
350 cos 30 = 303 N
the force in the direction of motion times the distance pulled is the work done.

How do I draw the diagram for this?

I got it, thanks though.
