Given that an object is undergoing variable-speed linear motion on a plane, and the relationship between displacement $s$ (unit: meters) and time $t$ (unit: seconds) can be represented by the function $s=\ln \left(t+1\right)+t^{2}-t$, then the instantaneous velocity of the object at $t=3$ seconds is ______ meters per second.
