Question:

Two identical springs of spring constant 280 N/m are attached to a block of mass 11 kg. The block is set oscillating on the frictionless floor. What is the frequency (in Hz) of oscillation?

Effective Spring Constant:

In physics, two or more springs are said to be in series when they're connected from end-to-end or point to point, and in parallel when they're connected side-by-side, in both cases, so as to act as a single spring. When they're connected in parallel, the resulting spring constants add up, and the equivalent is higher than each of them. However, when they're connected in series, the inverse of the spring constants satisfies a relation. This results in a final spring constant that's lower than each of the spring constants individually.

Let:

{eq}k_1 {/eq} = spring constant of the first spring, 280 N/m

{eq}k_2 {/eq} = spring constant of the second spring, 280 N/m

m = mass of the...
