**Problem Statement:**

Determine the rate, with respect to time, at which the centripetal acceleration is changing at the instant that \( s = 10 \, \text{cm/s} \) and is increasing at a rate of \( 3 \, \text{cm/s}^2 \), and the radius is \( 50 \, \text{cm} \) and is decreasing at a rate of \( 2 \, \text{cm/s} \).

**Centripetal Acceleration of a Particle in Circular Motion**

Given a particle moving in a circle, its centripetal acceleration \(q\) in cm/s\(^2\) is given by:

\[ q = f(s, r) = \frac{s^2}{r} \]

Where:
- \(r\) is the radius in cm.
- \(s\) is the speed of the particle in cm/s.

The quantities \(q\), \(s\), and \(r\) are all functions of time \(t\).

---

a) **Exercise: Write out the chain rule for \(\frac{dq}{dt}\).**
