What is the vertical acceleration of a paper airplane that is launched horizontally with an initial velocity of 2.3 m/s?

–9.8 m/s2
0 m/s2
2.3 m/s2
9.8 m/s2

The answer is:

The first option,

If the paper airplane is launched horizontally, there will be an additional acceleration acting on it, it's called gravitational acceleration, on earth, it's equal to , the negative sign is telling us that the acceleration is attracting the airplane to the ground (Earth surface). Earth's acceleration is acting in all the objects above the Earth surface.

Hence, the answer is the first option.

Have a nice day!
