Two particles execute simple harmonic motion of the same amplitude and frequency along close parallel lines. They pass each other moving in opposite directions each time the displacement of the first particle is 1/5 of its amplitude. What is their phase difference? Number n Units v Current Attempt in Progress An oscillator consists of a block attached to a spring (k = 334 N/m). At some time t, the position (measured from the system's equilibrium location), velocity, and acceleration of the block are x = 0.0633 m, v= -13.6 m/s, and a = -104 m/s. Calculate (a) the frequency of oscillation, (b) the mass of the block, and (c) the amplitude of the motion.

(a) If the SHM has period 3.08 s, at what amplitude of motion will the block and piston separate? (b) If the piston has an amplitude of 6.72 cm, what is the maximum frequency for which the block and piston will be in contact continuously?
