An oscillator consists of a block attached to a spring (k = 450.0 N/m). At some time t the position (measured from the system's equilibrium location),velocity, and acceleration of the block are x = 0.35 m, v = -13.50 m/s and a = -105.0 m/s2.
a) What is the frequency?
b) What is the mass of the block?
c) What is the amplitude of oscillation for the motion?
