Question

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 = 0.627, and the kinetic friction coefficient is µk = 0.419. The combined mass of the sled and its load is m = 351 kg. The ropes are separated by an angle f = 21°, and they make an angle ? = 32.1° 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?
