Chapter 6, Problem 6.25E
A sled with mass 12.00 kg moves in a straight line on a friction less, horizontal surface. At one point in its path, its speed is 4.00 m/s; after it has traveled 2.50 m beyond this point, its speed is 6.00 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 sled’s motion.
