SUMMARY
The work done by the rope on the sled is calculated using the horizontal component of the tension in the rope. Given a tension of 250 N at an angle of 30 degrees, the horizontal component is determined using the formula {(Tension)*cos(30 deg)}. The sled moves at a constant speed of 1.5 m/s for a time interval of 5.0 seconds, leading to the calculation of work done as {Tension Power Delivered} = {Tension Horizontal Component}*{Horizontal Speed} and subsequently {Tension Work Performed During Time Interval} = {Tension Power Delivered}*{Time Interval}. The final work done is 1,250 J.
