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