Asked by Daniel
One end of a spring is attached to the ceiling. The unstretched length of the spring is 10.0 cm. A 2.0 kg mass is hung from the other end of the spring. It is slowly lowered until it comes to rest. At this point the spring is 15 cm long.
(a) What is the stiffness (spring constant) of the spring?
(b) The mass is now pulled down until the length of the spring is 20.0 cm. It is released. What
is the acceleration of the mass at the instant when it is released?
(c) If the mass accelerated at a constant rate how fast would it be going when it reached the
equilibrium length of the spring? Explain why this is not actually what happens.
(d) (We now return you to your regularly scheduled assignment about energy). How fast is the
mass actually going when it reaches the equilibrium length of the spring?
