If x=at+bt^(2), where x is the distance ...

If `x=at+bt^(2)`, where `x` is the distance travelled by the body in kilometres while `t` is the time in seconds, then the units of `b` are

A

`km//s`

B

`kms`

C

`km//s^(2)`

D

`kms^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`[x]=[bt^(2)].` Hence `[b]=[x//t^(2)]=km//s^(2)`
