❤. At the top of its projectory, the direction of acceleration is vertically downwards and its value is 9.8m^-2.

The acceleration at the top of a projectile is equal to g = 9.8 m/s².
Let's see the detailed explanation:
- Let's assume that a projectile is thrown with the initial velocity 'u' at an angle of .
- The maximum height reached by the object in the projectile trajectory is
- At this max height (i.e. top of projectile), the Y axis velocity component will become zero and the X axis velocity will be .
- The net acceleration of the object at that height will be equal to gravity (i.e. g = 9.8 m/s²), and the acceleration vector will be directed vertically downwards towards earth surface.
Hope It Helps
