The adjacent diagram shows the velocity time graph of a body. During what time interval is the motion of the body accelerated. Find the acceleration in the time interval mentioned in part 'a'. What is the distance travelled by the body in the time interval mentioned in part a?


Answer :

The body is accelerated between 0 to 4 unit and 8 to 10 unit. Since velocity is changing as time changes


Acceleration is constant in part ‘a’


Acceleration = =


In part ‘a’ final velocity= 30


Initial velocity =0


Time interval is 4s


Acceleration = ms-2


=7.5 ms-2


Distance travelled is the area covered by the velocity time graph


So, In part ‘a’ area covered = 1/2 4


= 60 (m)
