Kinematics Question 332

Question: A body starts from rest and travels ’s’ m in 2nd second, then acceleration is

Options:

A) $ (2s)m/s^{2} $

B) $ (3s)m/s^{2} $

C) $ ( \frac{2}{3}s )m/s^{2} $

D) $ ( \frac{3}{2}s )m/s^{2} $

Show Answer

Answer:

Correct Answer: C

Solution:

$ {{S} _{n}}\text{=u+}\frac{a}{2}( 2n-1 ) $

$ \text{or, S=}\frac{a}{2}( 2\times 2-1 )\Rightarrow \text{a=}\frac{2}{3}\text{sm/}{{s}^{2}} $
