A baseball is thrown with a velocity at an angle $\theta$ with the horizontal. The horizontal component of its velocity in the absence of air resistance is A) v cos $\theta$ B) v cos $\theta$ - gt C) v² + 2gx D) v² - 2gx E) v sin $\theta$ - gt

Question

Quizplus · Accepted Answer

The horizontal component of velocity is given by v cos 𝜃, where v is the magnitude of the initial velocity and 𝜃 is the angle between the velocity vector and the horizontal direction. There is no acceleration in the horizontal direction due to air resistance, so the horizontal component of velocity remains constant. Therefore, the answer is v cos 𝜃.
