7 An outfielder throws a baseball toward the infield at an angle of 25 degrees to the horizontal. The initial velocity of the throw is 12 m/s. Find the horizontal and vertical velocity components

Respuesta :

The horizontal and vertical components of the ball's velocity vector are, respectively,

[tex]v_x=\left(12\dfrac{\rm m}{\rm s}\right)\cos25^\circ\approx10.9\dfrac{\rm m}{\rm s}[/tex]

and

[tex]v_y=\left(12\dfrac{\rm m}{\rm s}\right)\sin25^\circ\approx5.07\dfrac{\rm m}{\rm s}[/tex]

(I've rounded to 3 significant digits just because...)
