A wheel of radius 0.5 m rotates with a constant angular speed about an axis perpendicular to its center. A point on the wheel that is 0.2 m from the center has a tangential speed of 2 m/s.

a) Determine the angular speed of the wheel.

b). Determine the tangential speed of a point 0.3 m from the center of the wheel.

c). Determine the tangential acceleration of the point that is 0.2 m from the center.
