Answer

Answer:

-9.8 m/s²

Explanation:

Step1: Recall acceleration in projectile motion

In projectile - motion near the Earth's surface, the acceleration in the vertical direction ($a_y$) is due to gravity.

Step2: Identify gravitational acceleration value

The acceleration due to gravity near the Earth's surface is approximately $g=- 9.8\ m/s^{2}$, and this is the value of $a_y$ for an object in projectile motion. The negative sign indicates the direction is downward.
