Final answer:
To find the horizontal and vertical velocity components of the baseball hit by a major leaguer, trigonometric functions cosine and sine are used with the given initial speed and launch angle.
Step-by-step explanation:
The problem is a classic example of projectile motion in Physics, specifically covering the kinematics of a body thrown with an initial velocity at an angle to the horizontal.
For a major leaguer who hits a baseball at a speed of 30 m/s and at an angle of 36.9° above the horizontal (ignoring air resistance), the horizontal (vx) and vertical (vy) components of the baseball's velocity can be calculated using trigonometry:
- Horizontal component, vx = v × cos(θ) = 30 m/s × cos(36.9°)
- Vertical component, vy = v × sin(θ) = 30 m/s × sin(36.9°)
These components are important for determining the range, maximum height, and total time of flight of the baseball.
