A sled whose total mass with cargo is 30.0 kg rests on ice. The coefficient of static friction is 0.20, and the coefficient of kinetic friction is 0.15. The sled is attached to a rope, horizontally, in which the tension force is slowly increased. How much tension force applied by the rope will cause the sled to start moving?
T=F(fr) =μ(s) •m•g
