A piston in an automobile engine is in simpleharmonic motion. Its amplitude of oscillationfrom the equilibrium (centered) position is±7.16 cm and its mass is 1.765 kg.Find the maximum acceleration of the pistonwhen the auto engine is running at this rate.Answer in units of km/s2

Amplitude ( A ) = 7.16 cm = 0.0716 m Frequency ( n ) = 3440 rev/min = 3440 / 60 rev/sec Maximum acceleration of the piston = == A 4 . 9282.11 m/ . (0.0712)
