Question

A large motor in a factory causes the

floor to vibrate at a frequency of 10 Hz.
The amplitude of the floor's motion
near the motor is about 3.0 mm.
Estimate the maximum acceleration of
the floor near the motor.​

Answer 1

12 m/s²

Step-by-step explanation:

Maximum acceleration is a = Aω², where A is the amplitude and ω is the frequency.

a = (0.0030 m) (10 rev/s × 2π rad/rev)²

a = 12 m/s²
