Answer

Explanation:

Step1: Recall projectile - motion concept

In projectile motion near the Earth's surface, the only acceleration acting on the object in the vertical direction is due to gravity.

Step2: Know the value of gravitational acceleration

The acceleration due to gravity near the Earth's surface has a magnitude of approximately $9.8\ m/s^{2}$ and acts downwards. In the standard coordinate system where the upward direction is positive, the vertical acceleration $a_y=- 9.8\ m/s^{2}$.

Answer:

$-9.8\ m/s^{2}$
