Question

your car tire has a radius of .4 m and is rotating at 3.5 rev/s, when suddenly you press hard on the accelerator. after traveling 200 m, the tire's rotation has increased to to 6.0 rev/s. what was the tires angular acceleration?

Answer 1

\[\omega _{f}^{2} =\omega _{i}^{2} +2\alpha \theta \]

Answer 2

use r and translational distance to find theta

Answer 3

does that make sense?
