- A \(\sqrt{6} \mathrm{~m}\)
- B \(2 \mathrm{~m}\)
- C \(1 \mathrm{~m}\)
- D \(\sqrt{5} \mathrm{~m}\)
Answer & Solution
Correct Answer
(B) \(2 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{w}_{\mathrm{g}}+\mathrm{w}_{\mathrm{FT}}+\mathrm{w}_{\mathrm{s}}=\Delta \mathrm{KE}\) \(5 \times 10 \times 5-0.5 \times 5 \times 10 \times \mathrm{x}-\frac{1}{2} \mathrm{Kx}^2=0-0\) \(250=25 \mathrm{x}+50 \mathrm{x}^2\) \(2 \mathrm{x}^2+\mathrm{x}-10=0\)…
