If ` x= at + bt^(2)` , where `x` is the distance travelled 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
`[s]= [bt^(2)] rArr [b] = [x//t^(2)] = km//s^(2)`
