is measured in feet over t seconds.
(a) Find x(0) and x(3).
(b) At what time(s) is the particle changing direction for values of for t≥ 0? Justify your answer.
(c) What is the total distance traveled by the particle from t=0 to t= 3?
(d) Is the particle's speed increasing or decreasing at t = 3? Justify your answer.
(e) What is the average velocity of the particle from 1 = 0 tot = 3?
(f) What is the average acceleration of the particle from t=0 to t=3?
