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
v2 = u2 + 2as
2as = v2 - u2
s = (v2 - u2)/2a
so
answer is C) s = (v2 - u2)/ 2a
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.
