3 The position of a particle moving along a straight horizontal groove is given by x = 2 + t(t-3) for 0 < t < 5 where x is measured in metres and t in seconds. (i) What is the position of the particle at times t = 0, 1, 1.5, 2, 3, 4 and 5? [ii] Draw a diagram to show the path of the particle, marking its position at these times. (ii) Find the displacement of the particle relative to its initial position at these times.
