1. The problem statement, all variables and given/known data Jason walks 50 meters at constant velocity(towards the right) along a 1000 meter long hard an flat snowy surface with Uk = 0.30 while pulling on a rope attached to an empty sled of mass 10 kg. The sled is observed to follow close behind Jason. The rope remains horizontal(parallel to the surface) and taught the entire time. Just after Jason has finished walking 50 meters, he drops the rope out of hi hand and continues to run another 75 meters at the same constant velocity. The sled moves another 40 meters before coming to a full stop. Calculate the total work done on the sled during the time Jason and the sled move 50 meters together. 2. Relevant equations Fn = ma Fk = Uk x Fn W=F Cos @ D Wf = Wa + Wfk 3. The attempt at a solution I have an attempt at it but its been marked aqwardly so I don't know which parts are right.
