A spring is attached to a ceiling, and has a relaxed length of 25cm. When a mass m = 0.80 kg is attached to the spring it stretchesto an equilibrium length of L0 = 34 cm.

(a) Find the spring constant of the spring.

(b) I lift the mass until the spring returns to its relaxed length,and then release it. When the mass returns to the equilibriumlength, what is its speed?

(c) After I release the mass and it falls, what is the length ofthe spring when the mass reaches its lowest point?
