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 mu_s = 0.611, and the kinetic friction coefficient is mu_k = 0.435. The combined mass of the sled and its load is m = 276 kg. The ropes are separated by an angle phi = 26 degree, and they make an angle theta = 31.4 degree with the horizontal. Assuming both ropes pull equally...
