Note: this problem does not require a kinematics table, as it does not involve the angular velocity changing at all. Both answers only require a single equation which you can find in your book. 3. The tire of a car has a radius of 0.26m. As the car travels down the street, the wheel spins with an angular velocity of w-80rad/s. a. How ow many times does the wheel spin per second? b. How fast is a point on the edge of the tire moving, in meters per second? (Incidentally, this is equal to the speed of the car as it drives down the road.)
