Question

If a mass on a spring is 4 kg and the spring constant is 4 N/m, what would be its period?A. π/2 sB. 2π sC. 1 sD. π s

Answer 1

Given:

Mass, m = 4 kg

Spring constant, k = 4 N/m

Let's find the period.

To find the period, T, apply the formula:

$T=2\pi\sqrt{\frac{m}{k}}$

Where:

T is the period

m is the mass

k is the spring constant.

Thus, we have:

$\begin{gathered} T=2\pi\sqrt{\frac{4}{4}} \\ \\ T=2\pi\sqrt{1} \\ \\ T=2\pi \end{gathered}$

Therefore, the period is 2π seconds.
