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.

2. Relevant equations

W=FdcosI

3. The attempt at a solution

AC/AB= cos20degress

AC=ABcos20

=350cos20degrees

=39

W=HdcosI

= (5)(250cos20)

=1644J

The work done is 1644J

Is this solution correct?
