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.
