Question

Describe the change in vertical velocity of a horizontally-launched projectile over time.

A. As a projectile falls from its initial height, the vertical speed increases over time due to the force of gravity.

B. It is impossible to describe the change in vertical velocity of a falling object because it can't beliuneasured
accurately

C. As a projectile falls from its initial height, the vertical velocity remains constant

D. As a projectile falls from its initial height, the vertical velocity increases over time

Answer 1

A and D are both true.

B and C are both false.

Answer 2

Step-by-step explanation:

Both A and D are correct,

Provided that DOWN is the positive direction for velocity to increase, and air resistance is ignored.
