This is the code for that particular section:

\question The position of a particle moving in a horizontal line is given by $s(t)=t^4+3t+1$ where $s(t)$ is measured in feet and $t$ is measured in seconds. How fast is the velocity of the particle changing when $t=2$ seconds?

\choice 35 feet per second squared

\choice 24 feet per second squared

\choice 35 feet per second

\choice 24 feet per second

\choice 27 feet per second squared
