What will be the instaneous acceleration of an object thrown upward, when it reaches maximum height?

Explanation

To determine the instantaneous acceleration of an object thrown upward when it reaches its maximum height, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Motion**: When an object is thrown upward, it moves against the force of gravity until it reaches its maximum height. At this point, its velocity becomes zero before it starts to fall back down.

2. **Identify the Forces Acting on the Object**: The only force acting on the object during its upward and downward motion is the force of gravity. This force causes a constant acceleration directed downward.
