Q1. A spring of force constant k=2.5*10^2 N/m is suspended form a rigid support. An object o mass 1.00 kg is attached to the uns How far below the starting point is equilibrium position for the object.
How far down does the object move before it starts up again
what is the time of the oscillation?
What is the speed of object when it first reaches its equilibrium position?
When the object does reach an equilibrium position stretched spring and released.
