Physics - Rotation Question with Solution | TestHub

A small particle of mass $m$ is projected at an angle $\theta$ with the $\mathrm{x}$-axis with an initial velocity ${\mathrm{v}}_0$ in the $\mathrm{x}-\mathrm{y}$ plane as shown in the figure. At a time $t<\frac{v_0\sin \theta }{g}$, the angular momentum of the particle is where $\hat{\mathrm{i}},\hat{\mathrm{j}}$ and $\hat{\mathrm{k}}$ are unit vectors along $\mathrm{x},\mathrm{y}$ and $\mathrm{z}$-axis respectively.
