A body moves with a velocity of 2m/s for 5s , then its velocity uniformly increases to 10m/s 5s . Thereafter its velocity begins to decrease at a uniform rate until it comes to rest after 10s . Plot a v-t graph and d-t graph for the motion of the body. Mark the portions of the graph when the motion is uniform and when the motion is non uniform. From the graph find the total distance moved by the body after 2s and 12s and in the last 10s.
