A glider with mass m=0.200kg sits on a frictionless horizontal air track, connected to a spring of negligible mass with force constant k=5.00N/m. Suppose the glider is initially at rest at x=0, with the spring unstretched. Then you apply a constant force F⃗ with magnitude 0.583 N to the glider. What is the glider’s speed when it has moved to x=0.100m? If the 0.583 N force is removed when the glider reaches the 0.100 m point, at what distance from...
