Question

The angular elevation of an enemy's position on a hill h feet high is $beta$ . Show that is order to shell if the initial velocity of the projectile must not be less than

$[g h (1 + \sin β)]^{1 / 2}$
$[g h (1 - \sin β)]^{1 / 2}$
$[g h (1 + cosec β)]^{\frac{1}{2}}$
$[g h (1 - \cot \sec β)]^{\frac{1}{2}}$

The correct answer is: $left square bracket g h left parenthesis 1 plus text cosec end text beta right parenthesis right square bracket to the power of fraction numerator 1 over denominator 2 end fraction end exponent$

Let u be the velocity of projection. The coordinates of enemy’s position with reference to horizontal and vertical lines through the point of projection as the coordinates axes are $left parenthesis h cot invisible function application beta comma h right parenthesis$ For the projection to hit at $left parenthesis h cot invisible function application beta comma h right parenthesis$ we must have.
$u to the power of 2 end exponent greater or equal than g open square brackets h plus square root of h to the power of 2 end exponent cot to the power of 2 end exponent invisible function application beta plus h to the power of 2 end exponent end root close square brackets$
Þ $u to the power of 2 end exponent greater or equal than g left square bracket h plus h c o s e c beta right square bracket$ Þ $u greater or equal than square root of g h left parenthesis 1 plus cos invisible function application rightwards arrow over short leftwards arrow e c beta right parenthesis end root$ .
