Question

question 10 choose the best answer from the options that follow each question. for an object to be a projectile, it must be in free - fall and its initial velocity must have a horizontal component. start from rest. have both a vertical and a horizontal component. have either a vertical or a horizontal component.

Explanation:

A projectile is an object in free - fall. Its initial velocity can have only a vertical component (thrown straight up or down) or both vertical and horizontal components (thrown at an angle), so it must have either a vertical or a horizontal component. It doesn't have to start from rest, and it doesn't necessarily have to have a horizontal component.

Answer:

have either a vertical or a horizontal component.
