1. A bicycle wheel has rotated 32 degrees counterclockwise from the reference line. Is this angular position positive or negative? 2. You observe the wheels of a car as it moves past you from right to left. Do the wheels have a positive or negative angular velocity? 3. An object has an angular velocity of 1.0 rad/s and an angular acceleration of -.05 rad/s. Is the speed of its rotation increasing or decreasing? Why? 4. Is the angular speed of the hour hand of a clock greater than, less than, or equal to the angular speed of the minute hand? 1.
