Serway & Jewett — Angular Momentum: Problem 8

A 1.50-kg particle moves in the \( xy \) plane with a velocity of \( \vec{v} = (4.20 \hat{i} - 3.60 \hat{j}) \text{ m/s} \). Determine the angular momentum of the particle about the origin when its position vector is \( \vec{r} = (1.50 \hat{i} + 2.20 \hat{j}) \text{ m} \).
