What is the vertical acceleration of a paper airplane that is launched horizontally with an initial velocity of 2.3 m/s? a) –9.8 m/s2 b) 0 m/s2 c) 2.3 m/s2 d) 9.8 m/s2

A) -9.8 m/s²

Explanation:

A paper airplane is launched horizontally. Considering upward direction as positive and downward direction as negative, the vertical acceleration would be acceleration due to gravity acting downwards and thus, would be negative.

vertical acceleration = acceleration due to gravity = -9.8 m/s²
