A piston in an automobile engine is in simple harmonic motion. Its amplitude of oscillation from the equilibrium (centered) position is +/- 7.86 cm and its mass is 1.684 kg.
Question 1: Find the maximum velocity of the poston when the auto engine is running at the rate of 2480 rev/minute. Answer in units of km/s^2.
Question 2: Find the maximum acceleration of the piston when the auto engine is running at this rate. Answer in units of km/s^2.
