A Particle moves along the x-axis according to the expression x = 3t2 – 2t. Where x is in m and t is in s

(a) What is the displacement of the particle in the time intervals t = 0 to t = 1 s and t = 1 s to t = 4 s?

(b) Calculate the average velocity for the time interval in (a). (c) Find the instantaneous velocity of the particle at t = 3 sec.
