Question
The position of a particle
going along a line is
described by X = t3-6t2
-15t + 40, x in meters, t in
seconds. Positive x is on
the right of the reference
point; negative is on the
left. Where does the
particle (first) reverse its
direction?
60m on the left
0 m (on the
reference point)
40m on the right
48 m on the right
