Question

A ball whose mass is 1.9 kg is suspended from a spring whose stiffness is 8.0 N/m. The ball oscillates up and down with an amplitude of 17 cm. Part 1 (a) What is the angular frequency? ω= radians/s the tolerance is +/-2% By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor.

Answer 1

Answer:

2.05 radians/s

Explanation:

This is a simple harmonic motion. The angular frequency of a loaded spring is given by

$\omega = \sqrt{\dfrac{k}{m}}$

where $k$ is the spring constant and $m$ is the mass on the spring.

Using the known values,

$\omega = \sqrt{\dfrac{8}{1.9}} = 2.05$
