1. The problem statement, all variables and given/known data An Eskimo pulls a 100kg sled with a constant force through the snow at a constant speed of 1.5m/s. He applies this force by pulling on a rope at 30◦ to the horizontal. There is a coeﬃcient of kinetic friction between the sled and the snow of 0.1 1)Find the tension in the rope 2)What is the power due to the frictional force (rate at which energy is being dissipated) the instant he stops pulling on the sled 2. Relevant equations The Force of Tension = (mass)(acceleration) - (Coefficient of Friction)(-mass · gravity) 2) Power= Work/Time 3. The attempt at a solution 1) I thought it was a simple just plug it in, so i did Fτ=(100kg)(1.5m/s)-(.1)(-100kg*9.8)=248N 2) I used the 248N to find the amount of work that was done, so Work=248N*1.5m/s*Cos(30)=322.16. However after this I am confused as to how i find time.
