A heavy sled is being pulled by two people, as shown in the igure. The coefficient of static friction between the sled and he ground is µ, = 0.603, and the kinetic friction coefficient %3D 5 Hk = 0.395. The combined mass of the sled and its load is %3D 1 = 306 kg. The ropes are separated by an angle ø = 28.0°, %3D nd they make an angle 0 = 31.1° with the horizontal. Assuming both ropes pull equally hard, what is the minimum ope tension required to get the sled moving?
