Question

part a
the tangential speed of every point of a rotating rigid object
? view available hint(s)
is zero
is tangent to the circular motion
depends on the distance to the axis of rotation
is the same
submit
correct answers

Explanation:

The tangential speed \(v\) of a point on a rotating rigid - body is given by \(v = r\omega\), where \(r\) is the distance from the axis of rotation and \(\omega\) is the angular speed. Since \(\omega\) is the same for all points on a rigid - body in pure rotation, the tangential speed depends on the distance \(r\) to the axis of rotation.

Answer:

depends on the distance to the axis of rotation
