The spring was suspended vertically, and an object of mass of
0.80 kg was suspended at the lower end of it, slowly supported by
the hand and lowered to stop. The spring then extends by a distance
of 2.5 cm from its initial location.(Status of balance of
force)
1) What is the force constant of the spring?
2) What is the velocity of the object when it passes through the
equilibrium point of the force by pulling and releasing an
additional 3.0 cm from the top state?
