1. The problem statement, all variables and given/known data A 165N sled is pulled a distance of 205m. The task requires 5200J of work to overcome friction and is done by pulling a rope at what angle? Coefficient of friction is 0.25. 2. Relevant equations W= Fdcos@ (@ for theta) F= ma 3. The attempt at a solution My free body diagram had Force applied in the y direction (Fay) and normal force along the positive y axis and weight on the negative y axis. Force applied in the x direcrion (Fax) is on the positive x axis and the force of friction is on the negative y axis. I tried to solve for a variety of variables, but i can't get the right combination so two unknowns aren't in the same equation. I believe I need to find the force applied before I can get theta. I solved that Ff = Facos@ (Force applied in the x direction) For the y direction: Fasin@ = -N + W I solved for Fa then.. Fa= (-N+W)/sin@ I plugged that back into Ff= Facos@ Ff= cos@* (-N+W)/sin@ However, normal force is another unknown. I'm not sure where else to go from here. Thanks in advance.
