A missile starts from rest and travels along a straight track. It has an acceleration of a = 6t for
an interval between 0 and 5 second while for the next interval between 5 and 10 seconds, it
has an acceleration of a = 2t + 20 as shown in Figure Q1. Draw the v-t graph that describes the
motion of missile and find the distance traveled in 10 s.
