Calculate the angular momentum if `vecr=2hati-3hatj-4hatk and vecP= hati+hatj-5hatk`.

Explanation

To calculate the angular momentum \( \vec{L} \), we use the formula:

\[ \vec{L} = \vec{r} \times \vec{P} \]

where \( \vec{r} \) is the position vector and \( \vec{P} \) is the linear momentum vector.
