A bicycle wheel has an angular acceleration
of 1.4 rad/s2.
If a point on its rim has a tangential accel-
eration of 49 cm/s2, what is the radius of the
wheel?
Answer in units of m.
I know that there should be some way to relate the angular acceleration and the tangential acceleration but I can't figure it out.
I tried to relate the angular acceleration to angular speed to then find delta theta so then I could plug into S=Rtheta. The only problem is that I don't have the angular speed. I know that there has to be an easy way to do this problem.
