Vedclass · Answer

$\begin{array}{l}
R = \frac{{{u^2}{{\sin }^2}	heta }}{g},H = \frac{{{u^2}{{\sin }^2}	heta }}{{2g}};{H_{\max }}at2	heta  = 90\
{H_{\max }} = \frac{{{u^2}}}{{2g}}\,; = 10 \Rightarrow {u^2} = 10g 	imes 2\
R = \frac{{{u^2}\sin 2	heta }}{{\left( g ight)}} \Rightarrow {R_{\max }} = \frac{{{u^2}}}{g}\
{R_{\max }} = \frac{{10 	imes g 	imes 2}}{g} = 20\,meter
\end{array}$
