T = 2.25 s. = Time for i rev. = Period.

so T=2.25 secs/rev because that's the period for one revolution.
then use v=(2*pi*r)/ T to find v
Pi=3.14
r=radius 2.25/2=1.125
T=2.25
so v=3.14
then use your found v to find omega (w)
v(sub)t=r*w
so rearrange v(sub)t to get w
w=r*v(sub)t
w=1.125/3.14=0.358
then use v=(2*pi*r)/ T to find v
Pi=3.14
r=radius 2.25/2=1.125
T=2.25
so v=3.14
then use your found v to find omega (w)
v(sub)t=r*w
so rearrange v(sub)t to get w
w=r*v(sub)t
w=1.125/3.14=0.358
