Question

For general projectile motion, which of the following best describes the horizontal component of a projectile's velocity? assume air resistance is negligible.

Answer 1

Step-by-step explanation:

Lets take the u is the velocity of particle and this velocity make angle with horizontal is α.

So

The horizontal component of velocity will be u cos α.

The vertical component of velocity will be u sin α.

When particle reaches at the top most position then the vertical component of velocity will become zero ,only horizontal component will remains u cos α.

Answer 2

The answer to the given question above would be ZERO. For general projectile motion, the one that best describes the horizontal component of a projectile's velocity is this: The horizontal component of a projectile's acceleration is zero. Hope this answers your question.
