A steel block has a mass of 4.73 kg and slides along a smooth, level surface at 55 m/s. Find its kinetic energy. Answer in units of J. part 2 of 2 Initially the block was at rest on the sur- face. A constant force acted on it through a distance of 20 m to give it the speed of 55 m/s. What was the magnitude of the force? Answer in units of N.
