Question: A heavy sled is being pulled by two people, as shown in the figure. The coefficient of static friction between the sled and the ground

A heavy sled is being pulled by two people, as shown in the figure. The coefficient of static friction between the sled and the ground is ?s=0.579, and the kinetic friction coefficient is ?k=0.419. The combined mass of the sled and its load is ?=321kg. The ropes are separated by an angle ?=28.0, and they make an angle ?=30.1 with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension required to get the sledmoving?
