The displacement of a particle moving in...

The displacement of a particle moving in a straight line, is given by `s = 2t^2 + 2t + 4` where `s` is in metres and `t` in seconds. The acceleration of the particle is.

A

`2 m//s^2`

B

`4 m//s^2`

C

`6 m//s^2`

D

`8 m//s^2`

Text Solution

Verified by Experts

The correct Answer is:
B
`s = 2t^2 + 2t + 4, a = (d^2 s)/(dt^2) = 4 m//s^2`.
