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 vcosθ, where v is the magnitude of the velocity and θ is the angle with the horizontal. In the absence of air resistance, there is no horizontal force acting on the baseball, so the horizontal component of velocity remains constant. Therefore, the correct choice is A, which gives the horizontal component of velocity as vcosθ.
