Constraints and Friction (4 pts) You are pulling a sled with a kid on it at a constant velocity, holding the rope at an angle above the ground. (a) Draw a free body diagram of the scenario to illustrate the different forces affecting the sled. (b) What force must you exert by pulling the rope in order to make the sled move at a constant velocity? Express your answer in terms of the kinetic friction coefficient, k, the combined mass of the sled and the kid, m, the angle , and any other relevant physical constants
