As always, be sure to show all your work. What arc length does the Earth travel in a three-month period during its nearly circular 1.50 x 1011 m radius orbit around the Sun? A bicycle wheel rotates uniformly through 3.25 revolutions in 2.13 s. Find: Average angular speed of the wheel. Tangential speed at a point 0.152 m from the center (axis of rotation) of the wheel. A wheel is rotating with a constant angular acceleration of 3.50 rad/s2. If the initial angular velocity is 2.10 rad/s, find: Angular displacement after 4.86 s. Angular speed after 4.86 s.
