3 A particle moves along the x axis. Its position varies with
time according to the expression x = -4t + 2t² , where (x) is
in meters and (t) is in seconds.
o Determine the displacement of the particle in the time
intervals (t = 0) to (t =1 s) and (t = 1 s) to (t = 3 s).
o Calculate the average velocity during these two time
intervals.
o Find the instantaneous velocity of the particle at (t =
2.5 s).
