With the acceleration depicted in Fig. 2, a particle travels along a straight path. Plot the v-t and x-t curves for 0 < t < 15s. If the particle starts from the origin with an initial velocity of vo = -14 m/s, calculate (a) the particle's maximum velocity and (b) the particle's maximum position coordinate. 8 3 0 a (m/s2) 21 5 18 Fig. 2 t(s)
