A 200 g mass hangs from a spring with k A?value of 10N/m. At t=0 sec, the mass is 20 cm below the springs equilibrium position and moving upward at 100 cm/s.
a) What is the oscillation frequency?
b) What is the mass position at t= 1.0 sec?
c) What is the distance from the equilibrium position when v = 50 cm/s?
