1. The problem statement, all variables and given/known data What is the best angle to make pulling a block of mass M, possible with the least tension. Friction is applied, the coefficient varies, does the coefficient change the angle? for which is which angle best... 3. The attempt at a solution I solved Tension for two different equations T=(mg-Fn)/sin(0) and T= (Fn*coefficient of friction)/cos(0) but I haven't really gotten anywhere with it.
