Question

21) Rearrange the formula v2 = u2 + 2as for s. A) s = v2 + u2 2 B) s = v2 - u2 2 C) s = v2 - u2 2a D) s = v2 + u2 2a

Answer 1

v2 = u2 + 2as
2as = v2 -  u2
s = (v2 -  u2)/2a

so 
answer is C) s = (v2 - u2)/ 2a

Answer 2

Answer:

Option C is correct.

Step-by-step explanation:

Given the formula $v^2-u^2=2as$. we have to rearrange the formula for s.

$v^2=u^2+2as\\\\\\v^2-u^2=2as\\\\\text{Divide by 2a on both sides}\\\\2as=v^2-u^2\\\\s=\frac{1}{2a}(v^2-u^2)$

Hence, option C is correct.
