A particle thrown at angle ${45}^{\circ }$ with horizontal with speed $u$ has its range equal to $R$. At what angle should it be thrown with same speed for its range to be half of its initial value.

1. ${15}^{\circ }$
2. ${60}^{\circ }$
3. ${70}^{\circ }$
4. ${30}^{\circ }$

Q.

A projectile thrown with an initial speed \(u\) and angle of projection \(15^{\circ}\) to the horizontal has a range \(R\). If the same projectile is thrown at an angle of \(45^{\circ}\) to the horizontal with speed \(2u\), its range will be

Q. A projectile thrown with an initial speed $u$ and the angle of projection ${15}^o$ to the horizontal has a range $R$. If the same projectile is thrown at an angle of ${45}^o$ to the horizontal with speed $2u$, what will be its range?

Q.
