# A BODY COVERS 4m IN 3rd SECOND AND 12m IN 5th SECOND. CALCULATE THE ACCELERATION, IF IT IS ACCELERATED UNIFORMLY.

### Asked by swarajtopper | 30th Jul, 2015, 09:41: PM

Expert Answer:

### Given:
Distance moved in 3^{rd} second, s_{3} = 4 m
Distance moved in 5^{th} second, s_{5} = 12 m
By the equation of motion (uniform acceleration):
where S_{n} is the distance travelled by a body in the n^{th} second of its journey.
Therefore, the acceleration of the body is 4 m/s^{2}.

^{rd}second, s

_{3}= 4 m

^{th}second, s

_{5}= 12 m

_{n}is the distance travelled by a body in the n

^{th}second of its journey.

^{2}.
