The position function x(r) of a particle moving along an x axis is x = 4.0
Question:
The position function x(r) of a particle moving along an x axis is x = 4.0 – 6.0t2, with x in meters and t in seconds.
(a) At what time and
(b) Where does the particle (momentarily) stop? At what
(c) Negative time and
(d) Positive time does the particle pass through the origin?
(e) Graph x versus t for the range – 5s to + 5 s.
(f) To shift the curve rightward on the graph, should we include the term + 20t or the term – 20t in x(t) ?
(g) Does that inclusion increase or decrease the value of x at which the particle momentarily stops?
