Question

A projectile is projected with speed 20m/s making an angle 30 degree with the vertical .The speed when its direction of motion makes an angle 30 degree with the horizontal is

Answer 1

The speed of the projectile with the horizontal is 17.32 m/s.

Explanation:

Speed of the projectile, v = 20 m/s

The projectile is projected at an angle of 30 degrees

Let $v_x$ is the speed when its direction of motion makes an angle 30 degree with the horizontal. The horizontal speed of the projectile is given by :

$v_x=v\ cos\theta$

$v_x=20\times cos(30)$

$v_x=17.32\ m/s$

So, the speed of the projectile with the horizontal is 17.32 m/s. Hence, this is the required solution.
