Question

A 1.5 kg mass attached to an ideal spring oscillates horizonatlly with an amplitude of 0.30 m. The spring constant is 85 N/m. What is the period of the mass's motion?

Answer 1

T = 0.83 seconds

Step-by-step explanation:

Given that,

The mass attached to the spring, m = 1.5 kg

The amplitude of the spring, A = 0.3 m

The spring constant of the spring, k = 85 N/m

We need to find the period of the mass's motion. The time period in spring mass system is given by :

`T=2\pi \sqrt{(m)/(k)} \\\\T=2\pi \sqrt{(1.5)/(85)} \\\\T=0.83\ s`

So, the period of the mass's motion is 0.83 seconds.
