A sled with mass 13.6 kg moves in a straight line on a frictionless horizontal surface. At one point in its path, its speed is 4.01 m/s; after it has traveled a distance 3.21 m beyond this point, its speed is 8.31 m/s. (a) Use the work-energy theorem to find the magnitude of the force (in N) acting on the sled, assuming that this force is constant and that it acts in the direction of the sled's motion (b) Find the magnitude of the normal force (in N) acting on the sled?
