The acceleration-time graph of a particle moving along 
-axis is shown in the figure. If the
particle starts with velocity of 
at 
, find the velocity of the particle at 
.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
The velocity after 4 s will depend on the change in velocity of the particle in the interval 0 s to
4 s, which is given by the area under 
graph. Before calculating the area, let us find the acceleration at 
.
Change in velocity 
Area between 0 s to 4 s
final velocity 
initial velocity
