Unformatted text preview: fter it has traveled 2.50 m beyond this point, its speed is 6.00m/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. Mass of sled But we knot that work done by a body is Initial speed Final speed Displacement Force Substituting all the given values we get According to the work energy theorem we have EX 6.37 A 6.0-kg box moving at 3.0 m/s on a horizontal, frictionless surface runs into a light spring of force constant 75 N/cm.
