If a man has a velocity varying with time given as `v=3t^(2),v` is in `m//s` and `t` in `sec` then `:`

Find out his displacement after 2 seconds of his start `:`

A

10 m

B

6 m

C

12 m

D

8 m

Text Solution

Verified by Experts

The correct Answer is:
D

`underset(0) overset(s)(int) dS - underset(0) overset(2)(int) 3t^(2)dt`
`S=[t^(3)]_(0)^(2)=8`.
