The acceleration-time graph of a particle moving along a straight line is as shown in figure. At what time the particle acquires its initial velcoity ?

A

3 sec

B

5 sec

C

6 sec

D

16 sec

Text Solution

Verified by Experts

The correct Answer is:
C
Area of `a - t` graph gives `Delta vec(V)`, i.e., change in velocity. If `v_(f) = v_(i)`, as mentioned in the question then , `Deltav = 0 rArr "area" = 0`
