Q. No. 44 x c The velocity time graph of a particle moving along a straight line in a given time interval is as shown in figure. Then the particle (with increase in time starting from t = O sec.) speeds up v(m/s) t(s) (B) speeds down (D) first speeds up and then speeds down (C) first speeds down and then speeds up The variation of velocity of a particle moving along a straight line is shown in the figure. The distance travelled by the particle in 4 s is REDMI NOTE 5 PRO MI DUAL CAMERA v(m/8) 20 2019/5/20 12:14

Dear student,
                 In the above V vs T graph the slope of a straight line is constant. The slope of V vs T graph gives Acceleration .
                 so the Acceleration is constant...
                 In the above graph from t=0 to t=tnegative velocity constantly decreases and positive veloity increases...
                It means body velocity is slowing down and becomes ZERO at t=t and then velocity is increasing in opposite                          direction.....
                We can say it is speeding up in the same direction.....
