Question
A particle of mass $m$ is moving with velocity $\vec{v}$ along a line $y=x+5$. Find the angular momentum of the particle about a perpendicular axis passing through origin $O$.
Step 1
Comparing this with the equation of a line $y = mx + c$, we get $m = 1$. We know that $m = \tan(\theta)$, so $\tan(\theta) = 1$. Show more…
