# {{ params.vars.title }}
The position of a particle in centimeters is given by $s(t) = 20 - 9t + t^2$, where $t$ is in seconds.

## Part 1

Determine the net displacement in the first {{params.seconds}} seconds.

### Answer Section

Please enter in a numeric value in ${{ params.vars.units }}$.

## Part 2

Determine the total distance travelled in the first {{params.seconds}} seconds.

### Answer Section

Please enter in a numeric value in ${{ params.vars.units }}$.
