Vedclass · Answer

From ground

$\mathrm{R} =\frac{2 \mathrm{u} 	imes \mathrm{u}_{\mathrm{y}}}{\mathrm{g}} \Rightarrow 240=\frac{2 	imes 30 	imes \mathrm{u}_{\mathrm{y}}}{10} \Rightarrow \mathrm{u}_{\mathrm{y}}=40 \mathrm{m} / \mathrm{s}$

$	an 	heta=\frac{\mathrm{u}_{\mathrm{y}}}{\mathrm{u}_{\mathrm{x}}}=\frac{40}{30}=\frac{4}{3} $
