The sled is stuck in the snow. A child pulls on the rope and finds that the sled just barely begins to move when he pulls with a force of 24 N, with the rope at an angle of θ = 33° with respect to the horizontal. The mass of the sled is 14 kg.

If the child continues to pull on the sled and it has an acceleration of 0.31 m/s2, find the coefficient of kinetic friction between the sled and the snow.
