A body is thrown vertically upwards with an initial velocity u. Write an expression for the maximum height attained by the body.

Explanation

To derive the expression for the maximum height attained by a body thrown vertically upwards with an initial velocity \( u \), we can follow these steps:

### Step 1: Understand the motion
When the body is thrown upwards, it will rise until it reaches a maximum height where its velocity becomes zero. At this point, the body will start to fall back down.

### Step 2: Identify the variables
- Initial velocity, \( u \) (upwards)
- Final velocity at maximum height, \( v = 0 \) (the body stops momentarily)
