Are ω and \dot{θ} the same in a polar kinematics? I know ω is angular speed (rad/s) and it seems to me that \dot{θ} would be the same, but in the context of rotation in polar coordinates where v = \dot{r}\widehat{r}+ r\dot{θ}\widehat{θ}, v = rω, and vθ = r\dot{θ}, that doesn't seem to be...

ah, i see now that v1=0 as well, since point 1 is to be taken inside the can. I was mistakenly assuming v1 to be an exit velocity. i knew it was something simple. Thank you
