Question
The acceleration time graph of a particle moving along a straight line is as shown in Fig. At what time the particle acquires its initial velocity ?
Open in App
Solution
Given,
An Acceleration time graph,
So, the area under the velocity time graph shows the change in velocity,
Let the time
t
0
the particle accuire the initial velocity,
Therefore the change in velocity of the particle in the time
t
is:
So, Area under the velocity time graph is zero.
Thus Area of
