Estion 9 of 10 sapling learning 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 as = 0.587, the coefficient of kinetic friction is a = 0.405, and the combined mass of the sled and its load is m-291 kg. the ropes are separated by an angle φ= 24", and they make an angle 8 with the horizontal. assuming both ropes pull equally hard, what is the minimum rope. tension required to get the sled moving? number
