Question

A spring stretches 0.150 m when a 0.30 kg mass is hung from it. The spring is then stretched an additional 0.100 m from this equilibrium point and released. Determine a). the spring constant, k, b). the maximum velocity of the mass, c. ) the maximum acceleration of the mass, d.) the total mechanical energy of the mass, e.) the period and frequency of the mass and spring, and e.) the equation of time dependent vertical position of the mass.
