Question

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

Answer 1

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

`v_x=\left(12(\rm m)/(\rm s)\right)\cos25^\circ\approx10.9(\rm m)/(\rm s)`

and

`v_y=\left(12(\rm m)/(\rm s)\right)\sin25^\circ\approx5.07(\rm m)/(\rm s)`

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