A piston in an automobile engine is in simple

harmonic motion. Its amplitude of oscillation

from the equilibrium (centered) position is

卤3.76 cm and its mass is 1.382 kg.

Find the maximum velocity of the piston

when the auto engine is running at the rate of

2920 rev/min.

Answer in units of m/s.A piston in an automobile engine is in simple harmonic motion. Its amplitude of oscillation from the equilibri?omega = 2920 rev/min (min / 60 sec) (2pi rad/rev) = 305.8 rad/sec



v = A * omega * sin(omega * t) = 0.0376 m * 305.8 rad/sec * sin(305.8 * pi / 2)

v = 11.5 m/s
