Question

A boy can throw a stone up to a maximum height of $10\,m$. The maximum horizontal distance that the boy can throw the same stone up to will be :

• A. $20\sqrt{2}\,m$
• B. $10\,m$
• C. $10\sqrt{2}\,m$
• D. $20m$

Answer 1

Answer: (D)

$20m$

Answer 2

$h_{max}=\frac{u^{2}}{2g}=10$ $u^{2}=200 \,...\left(1\right)$ $R_{max}=\frac{u^{2}}{g}=20m$
