A monkey is pulling a dog on a sled at an angle of 60 degrees to the ground with a force of 90 N. The coefficient of static friction between the snow and the sled is 0.200. The total weight on the sled that the monkey is pulling the dog on is 110 N. Is the sled at a constant velocity or is the sled accelerating? If the sled is accelerating, what is the acceleration of the sled in m/s^2? (The answer is a = 3.44 m/s^2, want to see the work to get there).
