    4 kg steel ball accelerated to 62 m/s and experimental train kinematics

    A steel ball has a mass of 4 kg and rolls along a smooth level surface at 62 m/s. a) Find its kinetic energy ( i found this.. ) b) At first, the ball was at rest on the surface. A constant force acted on it through a distance of 22 m to give it the speed of 62 m/s. What was the magnitude...
