A particle moves along a line with velocity function v(t) = 3t^2 - 6t, where v is measured in meters per second. a) Find the displacement of the particle in the time interval [0,5]. b) Find the total distance traveled by the particle in the time interval [0,5].

Give the positions $s=f(t)$ of a body moving on a coordinate line, with $s$ in meters and $t$ in seconds. a. Find the body's displacement and average velocity for the given time interval. b. Find the body's speed and acceleration at the endpoints of the interval. c. When, if ever, during the interval does the body change direction? $$s=-t^{3}+3 t^{2}-3 t, \quad 0 \leq t \leq 3$$
