Motion Along a Line In Exercises 81-84, the function s ( t ) describes the motion of a particle along a line. (a) Find the velocity function of the particle at any time t ≥ 0 . (b) Identify the time interval (s) on which the particle is moving in a positive direction. (c) Identify the time interval(s) on which the particle is moving in a negative direction, (d) Identify the time(s) at which the particle changes direction. s ( t ) = t 3 − 20 t 2 + 128 t − 280
