# Problem: A projectile is launched at an angle of 30 degrees above the horizontal at a speed of 300 m/s. In what direction is it traveling after 3 s? In other words, what is the direction of its velocity vector? (Use |g| = 10 m/s2.)

###### FREE Expert Solution

The direction of the projectile's velocity vector after traveling for 3s is found from:

$\overline{){\mathbf{t}}{\mathbf{a}}{\mathbf{n\varphi }}{\mathbf{=}}\frac{{\mathbf{v}}_{\mathbf{f}\mathbf{y}}}{{\mathbf{v}}_{\mathbf{f}\mathbf{x}}}}$
