Question

What is the maximum acceleration of a platform that oscillates with an amplitude of 2.5 cm at a frequency of 8.6 Hz? find max speed and accel.

Answer 1

Max speed is given by:
\[Speed _{\max} = A \omega \]
where A: Amplitude in meters
omega: angular frequency
You can find angular frequency using:
\[\omega = 2\pi f\]
where f is the frequency. Similarly maximum acceleration is given by:
\[a _{\max} = A \omega ^{2}\]

Thanks I new I was missing something
