Answer to Question #292957 in Physics for Meep

Question

The angular velocity of a wheel rotating on a horizontal axle point west. In what direction is the linear velocity of a point on the top of the wheel? If the angular acceleration points east, describe the tangential linear acceleration of this point at the top of the wheel. Is the angular speed increasing or decreasing?

Answer 1

The linear velocity of a point on the top of the wheel pints into the page.

The tangential linear acceleration of this point at the top of the same wheel points out of the page. The angular speed is decreasing.
