A good name for this would be appreciated

Classical Mechanics Level 2

A particle moved in a straight line so that position $x$ cm relative to $O$ at time $t$ seconds is given by $x = t^3 - 6t^2 +5, t \geq 0$ . Find the sum of the magnitudes of its initial position, speed and acceleration. If velocity or acceleration point in the minus $x$ direction, add that magnitude as a negative value to the sum.
