The acceleration `a` (in `ms^(-2)`) of a body, startin gfrom rest varies with time `t` (in s) following the equation `a = 3t + 4`. The velocity of the body at time `t = 2s` will be:

A

`10 ms^(-1)`

B

`18 ms^(-1)`

C

`14 ms^(-1)`

D

`26 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C

`a = 3t + 4`
`(dv)/(dt) = 3t + 4`
`v = (3t^(2))/(2) + 4t`
