A car of mass 1000 kg is moving with a velocity of 10 m/s. If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of the car at the end of 25 s will be: (a) 40 m/s
(b) 25 m/s
(c) 10 m/s
(d) 250 m/s​

Since the velocity-time graph is a horizontal line the velocity is constant. Since it is moving at 10m/s and this is constant then at 25s the car is still moving at 10m/s. The answer is c.
