the following table reprsents the velocity of a moving body at different instant of time.time-0,5,10,15,20,25,30
velocity-m/s-10,15,20,20,30,15,0.draw vt garaph and 1.for which interval of time the body has a uniform motion?find velocity in this time interval,the body has accelerated motion?calculate the acceleration.,

Answer:
According to above graph we conclude that the body has uniform motion from t=10 s to t=15 s in part 'bc'. Velocity is constant and is equal to 20ms
−1
during this interval.
