Question:

An oscillator consists of a block attached to a spring (k = 400 N/m). At some time t, the position (measured from the system's equilibrium location), velocity, and acceleration of the block are x = 0.100 m, v = – 13.6 m/s, and a = – 123 m/s2. Calculate
(a) The frequency of oscillation,
(b) The mass of the block, and
(c) The amplitude of the motion.
