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.
