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 \theta.

  • The maximum height reached by the object in the projectile trajectory is \boxed{H=\dfrac{u^{2}\sin^{2}(\theta)}{2g}}

  • At this max height (i.e. top of projectile), the Y axis velocity component will become zero and the X axis velocity will be u\cos(\theta).

  • 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.
