Homework Help: Physics

In 9.7 s a fisherman winds 2.1 m of fishing line onto a reel whose radius is 30 cm (assumed to be constant as an approximation).
The line is reeled in at constant speed.
Determine the angular speed of the reel in rad/s.
Thank you.

speed tangential=2.1/9.7 m/s

tangential speed= w*r

anglar speed=tangenital speed/radius

I'm still confused.
to find angular speed =
tnngenital speed/radius, would the radii cancel out, leaving only the tangential speed?

still confused as to set up
