Question

Any projectile always has a constant vertical acceleration of _______.

A. 9.81 m.s^2
B. 0 m/s^2
C. -9.81 m/s^2
D. It is not constant.

Answer 1

The answer to your question is: C. -9.81 m/s²

Step-by-step explanation:

A. 9.81 m/s² acceleration is considered positive when it goes to the center of the earth, so this option is incorrect.

B. 0 m/s² This option is incorrect because acceleration is 0 for a linear motion without acceleration.

C. -9.81 m/s² If a projectile goes to the sky, then the acceleration will be negative.

D. It is not constant. Acceleration is constant.
