- Homework Statement
- A 2.5kg particle travels at a constant speed of 5m/s along the line shown in the figure. What is the magnitude of the particle’s angular momentum calculated from the origin?

A.10kg*m^2/s

B.24 kg*m^2/s

C.30 kg*m^2/s

D.32 kg*m^2/s

E.40 kg*m^2/s

- Relevant Equations
- L=l* ω, ω= Θ/t, α= ΔΘ/Δt

First, I have always consider that the angular momentum equals to inertia times angular velocity, but that’s not the case from the options perpective, is my memory wrong, or is there something wrong with the options?

Another, I think I need to figure out the angle it went through, I think it has something to do with trigonometry, but I am not sure, and I cannot find a way to solve it.

Can anyone can help me with this? Thank you very much.
