Question

a mass on a spring bobs up and down over a distance of 17 cm from the top to the bottom of its path once each second. what are its period and amplitude?

Answer 1

The distance covered by bob from top to bottom is the half of the amplitude of motion of bob. Therefore, the amplitude of motion of bob is 17 cm/2=8.5 cm.

The bob completes one complete revolution in one second therefore, the time period of motion of bob is 1.0 s.
