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 6.0kg box moving at 3.0 m/s on a horizontal, frictionless surface runs into a light spring of force constant 75 N/cm.
