1) .6 kg object is hung from a spring with a force constant of 25 N/m. Calculate the displacement of the spring from its equilibrium length, assuming it is hung vertically and neglecting the spring mass. 2) The mass in (1) is pulled downward by an additional 6 cm and held there. Find the potential energy input corresponding to this additional displacement. 3) If the object is released, calculate the period of oscillation of the mass/spring system.

3kg mass is suspended from a spring It oscillates with period=6 seconds when it is pulled 0.1m below equilibrium 1. What is the time taken to move from 0.035 m below equilibrium position to 0.035 m above it when moving upwards 2. What is the total mechanical energy of this motion? 3. The motion of the mass is stopped, and the mass is removed. How much does the spring shorten?
