An oscillator consists of a block attached to a spring (k = 312 N/m). At some time t, the position (measured from the system's equilibrium location), velocity, and acceleration of the block are x = 0.0792 m, v = -13.5 m/s, and a = -142 m/s2. Calculate (a) the frequency of oscillation, (b) the mass of the block, and (c) the amplitude of the motion. (a) Number i (b) Number i (c) Number i eTextbook and Media Units Units Units O + 8
