Two people are pulling a sled with the help of a bar. The front of sled is connected to the bar with the help of two ropes at the two ends of the bar. The ropes attach to a single point on the sled. The angle between the two ropes is phi, whereas the angle ropes make with the plane of the surface is theta. 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=0.571 , and the kinetic friction coefficient is k=0.443 . The combined mass of the sled and its load is =291 kg . The ropes are separated by an angle =28.0° , and they make an angle =29.7° with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension required to get the sled moving? If this rope tension is maintained after the sled starts moving, what is the sled's acceleration?
