A spring with a spring constant 23 N/m is suspended vertically. (Assume the mass of the spring is negligible)
a) How much does the spring stretch (in cm) when 236 g is added?
The spring is then set into vertical oscillation from its equilibrium position with an intitial speed of 4 m/s.
b) What is the frequency of oscillation?
c) What is the amplitude of oscillation?
d) Write the equation of motion for the oscillating spring.
e) What is the total energy of the spring ?
