The velocity – time graph of a truck is plotted below:
​​​​​
  1. Calculate the magnitude of displacement of the truck in 15 seconds.
  2. During which part of the journey was the truck decelerating?
  3. Calculate the magnitude of average velocity of the truck

dear Student,
                    (1) We know that area under the v-t curve give the displacement hence d=12×4×5+7×4+12×3×4=44m(2)  during 12 to 15 s truck is decelerating as velocity is decraesing(3) average velocity=total displacement total time=4415=2.93m/s
