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

A

12 sec.

B

5 sec.

C

8sec.

D

16sec.

Text Solution

Verified by Experts

`a=10-(5)/(2)t`
Now dv=adt, integrating we have,
`10-(5)/(4)t^(2)=0`
`rArrt=0` or 8 sec. Accepted value 8 sec.
