Question

The angular velocity of a wheel rotating on a horizontal

axle points 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?
