Question

Velocity of train in first four hours is 60 km/h * r , 70 km/h * r, 80 km/h * r , 90 km/h * r Then what you can say about acceleration? And what type of line you will obtain by Drawing a graph of velocity - time?​

Answer 1

initial and final velocities. (Figure) illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate. The average velocity during the 1-h interval from 40 km/h to 80 km/h is 60 km/h:
