A body is projected at angle of `45^(@)` to the horizontal . What is its velocity at the highest point ?

Explanation

To find the velocity of a body projected at an angle of \(45^\circ\) to the horizontal at its highest point, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components of Velocity**:
When a body is projected at an angle, its initial velocity \(u\) can be broken down into two components:
- Horizontal component: \(u_x = u \cos(45^\circ)\)
- Vertical component: \(u_y = u \sin(45^\circ)\)
