Your car tire is rotating at 4.0 rev/s when suddenly you press down hard on the accelerator. After traveling 300 m, the tire’s rotation has increased to 6.5 rev/s . The radius of the tire is 32 cm.
A) What was the tire’s angular acceleration? Give your answer in rad/s²?
ANSWER: α=0.55 rad/s²
We are given an initial angular velocity of 4.0 rev/s and a final angular acceleration of 6.5 rev/s. Convert this angular velocities to rad/s.
The car traveled . Solve for the angular displacement
Solve for the angular acceleration
