Question: The plunger of a pinball machine has mass 0.440 kg and is attached to a spring of force constant 132.0 N/m. The spring is compressed a distance 8.0 cm from its equilibrium position x = 0 and released. A ball of mass 0.308 kg is in contact with the plunger when it is released.
Part A: At what distance xf from equilibrium will the plunger come to rest momentarily?
I need help to find at what distance xf from equilibrium will the plunger come to rest momentarily.
