A ball is thrown vertically upward. At the highest point of its pathe, what will be its (i) instantaneous velcity and (ii) instan-tanceous accekeratuib ? Conmment.

Explanation

To solve the problem, we need to analyze the motion of a ball thrown vertically upward and determine its instantaneous velocity and instantaneous acceleration at the highest point of its trajectory.

### Step-by-Step Solution:

1. **Understanding the Motion**:
- When a ball is thrown vertically upward, it moves against the force of gravity until it reaches its highest point. At this point, the ball momentarily stops before it starts descending.

2. **Instantaneous Velocity at the Highest Point**:
...
