Physics

A heavy sled is being pulled by two people, as shown in thefigure. The coefficient of static friction between the sled and theground is μs=0.587 , and the kinetic friction coefficient isμk=0.403 . The combined mass of the sled and its load is m=351 kg .The ropes are separated by an angle ϕ=26.0° , and they make anangle θ=30.4° with the horizontal. Assuming both ropes pull equallyhard, what is the minimum rope tension required to get the sledmoving?If this rope tension is maintained after the sled startsmoving, what is the sled's acceleration?
