## Homework Statement

The suspension of a modified baby bouncer is modelled by a model spring AP with stiffness k1 and a model damper BP with damping coefficient r. The seat is tethered to the ground, and this tether is modelled by a second model spring PC with stiffness k2.

The bouncer is suspended from a fixed support at a height h above the floor.

Determine the natural angular frequency of the system to two decimal places.

Values of k1, k2 and m are given.

## Homework Equations

- I know natural angular frequency ω = √(k/m)

## The Attempt at a Solution

With one fixed spring, I can find ω, but not sure what happens with two fixed springs. I tried adding k1 and k2 together, but got an integer answer that requires no rounding.
