- Homework Statement:
- An automobile travels to the right at a constant speed of 48 mi/hr. If the diameter of a wheel is 22 in., determine the velocities of points B,C,D, and E on the rim of the wheel.

- Relevant Equations:
- V_b = V_a + (w)X(R_ab)

The solutions used the spend of the wheel and its radius to find the angular velocity. I’m confused because I thought to find angular velocity you use the speed at the points of the radius not the translation speed of the wheel itself. Can someone explain this to me plz
