Angular Frequency of Springs in Series

Question

A block of mass *m* is attached to two identical springs, each with spring constant *k*, that are connected in series. The block oscillates on a frictionless horizontal surface. What is the angular frequency of the system?

Accepted Answer

$$\omega = \sqrt{\dfrac{k}{2m}}$$

Answer

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

Answer

$$\omega = \sqrt{\dfrac{k}{4m}}$$
