Question

A 1.5kg mass attached to an ideal spring oscillates horizontally with an amplitude of 0.50m. The spring constant is 85 n/m. what is the frequency of the mass's motion?

Answer 1

Answer:

frequency of the mass motion $f$ ≅ 1.2 Hz

Explanation:

Given that:

Mass m = 1.5 kg

Amplitude A = 0.50 m

Spring constant k = 85 n/m

The frequency can be calculated by using the formula:

$f = \frac{1}{2 \pi} \sqrt{\frac{k}{m} }$

$f = \frac{1}{2 \pi} \sqrt{\frac{85}{1.5} }$

$f = 1.198$ Hz

frequency of the mass motion $f$ ≅ 1.2 Hz
