Your car tire is rotating at 3.4 rev/s when suddenly you press
down hard on the accelerator. After traveling 240 m, the tire's
rotation has increased to 6.6 rev/s. The radius of the tire is 32
cm.
What was the tire's angular acceleration? Give your answer in
rad/s^2.
Express the answer using two significant digits.
The answer I got is, approximately, 0.013405, but, apparently,
it's wrong.
