If ` x= at + bt^(2)` , where `x` is the distance rtravelled by the body in kilometer while `t` is the time in seconds , then find the units of `b`.

A

`(km)/(s)`

B

`km-s`

C

`(km)/(s^2)`

D

`km-s^2`

Text Solution

Verified by Experts

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