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.

A projectile thrown at an angle of ${30}^{\circ }$ with the horizontal has a range $R_1$. Another projectile thrown, with the same velocity, at an angle ${30}^{\circ }$ with the vertical, has a range $R_2$. The relation between $R_1$ and $R_2$ is

Q. The horizontal range of a projectile fired at an angle of ${15}^{\circ }\text{is}50m$. If it is fired with the same speed at an angle of ${45}^{\circ }$, its range will be

Q. The horizontal range of a projectile fired at an angle of 15° is 50 m. If it is fired with the same speed at an angle of 45°, its range will be:

Q. A projectile thrown at an angle of ${30}^o$ with the horizontal has a range $R_1$ and attains a maximum height $h_1$ . Another projectile thrown, with the same speed, at an angle ${30}^o$ with the vertical, has a range $R_2$ and attains a maximum height $h_2$ . The relation between $R_1$ and $R_2$ is :-
