A circular racetrack has a radius of $r = {{ params.r }} \ \rm{m}$.
A race car races at a speed of $v = {{ params.va }} \ \rm{m/s}$.
For a short distance starting at $s = 0 \ \rm{m}$, the race car increases its velocity at $\dot v = {{ params.vad }}.s \ \rm{m/s^2}$.\
What is the speed and magnitude of its acceleration when it has moved $s = {{ params.s }} \ \rm{m}$

## Part 1

### Answer Section

Please enter in a numeric value in $m/s$.

## Part 2

### Answer Section
