Problem: A sled with mass 12.10 kg moves in a straight line on a frictionless horizontal surface. At one point in its path, its speed is 4.51 m/s ; after it has traveled a distance 2.51 m beyond this point, its speed is 6.61 m/s .Use the work-energy theorem to find the force acting on the sled, assuming that this force is constant and that it acts in the direction of the sleds motion.
