Question
**Problem Statement:**

The motion of a mass on a spring is described by the differential equation:

\[ 3y'' + 4y = 0 \]

with initial conditions:

\[ y(0) = 5, \quad y'(0) = 6. \]

*Question:* What is the amplitude of the resulting oscillations?

**Solution:**

The amplitude is given by 

\[ \sqrt{r} \]

where \( r = \underline{\hspace{20mm}}. \)

**Instructions:**

- Provide your answer for \( r \) in the space provided.
