A spring of spring constant k = 2,0x102 N/m is suspended with its upper end supported vertically from a ceiling. With the spring hanging in its
equilibrium configuration, an object of mass m = 2,0 kg is attached to the
lower end and released from rest. What is the speed of the object
after it has fallen 4.0 cm?
Hint: use this relation: dK + dU grav+ dUel = 0)
