Two projectiles `A` and `B` are thrown from the same point with velocities `v` and `v/2` respectively. If `B` is thrown at an angle `45^(@)` with horizontal.What is the inclination of `A`.when their ranges are the same?

Options

A. `sin^(-1)((1)/(4))`
B. `(1)/(2) sin^(-1)((1)/(4))`
C. `2 sin^(-1)((1)/(4))`
D. `(1)/(2) sin^(-1)((1)/(8))`

Answer

b

Explanation

`(v^(2))/(4g)=(v^(2)sin2 theta)/(g)`
