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}} $
