A body starting from rest moving with uniform acceleration has a displacement of `16 m` in first `4` seconds and `9 m` in first `3` seconds. The acceleration of the body is :

A

`1ms^(-1)`

B

`2ms^(-2)`

C

`3ms^(-2)`

D

`4ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`s_(n) = a(n-(1)/(2)),s = (1)/(2)an^(2)`
