A rocket engine has a specific impulse of $I_{sp} = 320\text{ seconds}$. The effective exhaust velocity ($v_e$) is related to specific impulse by $v_e = I_{sp} \cdot g_0$, where $g_0 \approx 9.81\text{ m/s}^2$ is the standard acceleration due to gravity. What is the effective exhaust velocity of the rocket engine in kilometers per second ($\text{km/s}$)?
