Question

At the top of the trajectory of a projectile, the acceleration is :

• A. Maximum
• B. Minimum
• C. Zero
• D. $g$

Answer 1

The correct option is D $g$

When the object is thrown from the ground, the acceleration due to gravity is constant on the object though out its flight. So the acceleration of the projectile is equal to the acceleration due to gravity, 9.81 meters/second/second, from just after its thrown, through its highest point, and until just before it hits the ground.
