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 μs = 0.643, the coefficient of kinetic friction is μk = 0.405, and the combined mass of the sled and its load is m = 351 kg. The ropes are separated by an angle ϕ = 25∘, and they make an angle θ with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension Tmin required to get the sled moving? Tmin =
