2. ### What are the max velocity and acceleration to which the pilot is subjected if the frequency is set at 27.4 Hz and the amplitude at 1.70 mm?

For simple harmonic motion, maximum velocity = ω*A and maximum acceleration = ω^2 * A Where A is amplitude and ω is angular velocity = 2pi * frequency 2pi(27.4 s^-1)(0.00170 m) = 0.293 m/s [2pi(27.4 s^-1)]^2 * (0.00170 m) = 50.4 m/s^2
