According to the velocity-time graph given below, what is the initial velocity of the car?
2 m/s
1 m/s
1.5 m/s
0 m/s
The initial velocity is the y-intercept of the graph at t = 0. It is 1.5 m/s in the graph.
A car of mass 1000 kg is moving with a velocity of v=10ms−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 :
(a) 25 m s−1
(b) 40 m s−1
(c) 10 m s−1
(d) 250 m s−1
