A spring stretches 2.0 cm when a 500 g mass is hung from one end.
a) What is the spring constant?
300 more grams are added to make the mass a total of 800g
b) What is the total amount of stretch now?
c) How much stored potential energy does the spring have now? d) If we start the mass bobbing up and down with simple harmonic motion, what is the frequency of the oscillation in Hz?
