In an electric shaver, the blade moves back and forth over a distance of 2.00 mm. The motion is simple harmonic, with frequency 120 Hz. Find (a) the amplitude, (b) the maximum blade speed, and (c) the maximum blade acceleration.

(a) The amplitude xm is half of the distance between the extremes of the motion.
So, xm = 2.00 mm/2
= 1.00 mm
Therefore the amplitude of oscillation would be 1.00 mm.
