Question

Find the angle of projection of a projectile motion having same values of horizontal component and vertical component of velocity of projection.

• A. ${60}^{\circ }$
• B. ${30}^{\circ }$
• C. ${45}^{\circ }$
• D. ${37}^{\circ }$

Answer 1

The correct option is C ${45}^{\circ }$

We know that in a projectile motion
$\tan \theta =\frac{u_y}{u_x}$
But, $u_x=u_y$
$\Rightarrow \tan \theta =1$
$\Rightarrow \theta ={45}^{\circ }$
$\therefore$ Angle of projection $={45}^{\circ }$
