प्रश्न
A car of mass 1000 kg is moving with a velocity of 10 m s−1. 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 will be :
विकल्प
25 m s−1
40 m s−1
10 m s−1
250 m s−1
उत्तर
It is given that the velocity time curve is parallel to x axis hence velocity is constant with time and acceleration is 0. So, the answer is
(c) 10 m s−1
