The position of an object moving along an x axis is given

Chapter , Problem 5

(choose chapter or problem)

The position of an object moving along an x axis is given by \(x=3 t-4 t^{2}+t^{3}\), where x is in meters and t in seconds. Find the position of the object at the following values of t:

(a) 1 s,

(b) 2 s,

(c) 3 s, and

(d) 4 s.

(e) What is the object’s displacement between t = 0 and t = 4 s?

(f) What is its average velocity for the time interval from t = 2 s to t = 4 s?

(g) Graph x versus t for \(0 \leq t \leq 4 \mathrm{~s}\) and indicate how the answer for (f) can be found on the graph.
