A football is kicked into the air vertically upwards. What is its (a) acceleration, and (b) velocity at the highest point ?

Explanation

To solve the problem of a football kicked vertically upwards, we need to determine two things: (a) the acceleration at the highest point and (b) the velocity at the highest point.

### Step-by-Step Solution:

1. **Understanding the Motion**:
- When the football is kicked upwards, it moves against the force of gravity. The motion is vertical, and we can assume that the only force acting on the ball after it is kicked is gravity.

2. **Acceleration at the Highest Point**:
