A car is moving with a velocity of 10 m / s e c 10 m/sec . Its mass is 1000 k g 1000 kg . If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of car at the end of 25 s e c 25 sec will be:

10 m/sec 15m/sec 40m/sec 25 m/sec

The horizontal line parallel to time axis means velocity is constant.Hence,v=10m/sec.

The velocity time graph is horizontal so accelation is 0 ,bz slope of velocity time graph is accelation.so velocity is constant.

the velocity time-graph is a horizontal line when acceleration is zero hence velocity remains same i.e 10m/s

Horizontal means it's a constant

velocity-time graph is a horizontal line parallel to time axis which means that it is moving with constant velocity...so it will have the same velocity at the end of 25secs
