The range of projectile at an angle q is equal to half of the maximum range if thrown at the same speed. The angle of projection q is given by –

A

150

B

300

C

600

D

Insufficient data

Answer

150

Explanation

Solution

max =u2g\frac{u^{2}}{g}

u2sin2θg\frac{u^{2}\sin_{2}\theta}{g} = 12\frac{1}{2} u2g\frac{u^{2}}{g}

q = 150
