A spring is hanging from the ceiling. Attaching a 560 g mass to the spring causes it to stretch 22.0 cm in order to come to equilibrium.
a.) What is the spring constant?
b.) From equilibrium, the mass is pulled down 10 cm and released. What is the period of oscillation?
c.) What is the maximum speed of the mass?
d.) At what position or positions does it have this speed?
