Write the unit vector in the direction of `vecA=5veci+vecj-2veck`.

Explanation

To find the unit vector in the direction of the vector \(\vec{A} = 5\hat{i} + \hat{j} - 2\hat{k}\), we will follow these steps:

### Step 1: Identify the vector components
The vector \(\vec{A}\) has the following components:
- \(A_x = 5\) (coefficient of \(\hat{i}\))
- \(A_y = 1\) (coefficient of \(\hat{j}\))
- \(A_z = -2\) (coefficient of \(\hat{k}\))
