A) \[~y=2x-5{{x}^{2}}\]
B) \[~y=x-5{{x}^{2}}\]
C) \[~4y=2x-5{{x}^{2}}\]
D) \[~y=2x-25{{x}^{2}}\]
Correct Answer: A
Solution :
\[\tan \theta =\frac{u\sin \theta }{u\cos \theta }=\frac{2}{1}\] The desired equation is \[y=x\tan \theta -\frac{g{{x}^{2}}}{2{{u}^{2}}{{\cos }^{2}}\theta }\]of \[y=2x-\frac{10{{x}^{2}}}{2{{(\sqrt{{{2}^{2}}+{{1}^{1}}})}^{2}}{{\left( \frac{1}{\sqrt{5}} \right)}^{2}}}\]or \[y=2x-5{{x}^{2}}\] Hence, the correction option is [a].
