2024 TWO(b)

An object is travelling in a straight line. Its displacement, in metres, is given by the formula

$s(t)=\ln (3t^2+5t+2)$, where $t>0$ and $t$ is time, in seconds.

Find the velocity of this object when $t=1$ second.

*You must use calculus and show any derivatives that you need to find when solving this problem.*
