suppose a disk rotates at constant angular velocity. (a) does a point on the rim have radial and/or tangential acceleration? explain. (b) if the disk's angular velocity increases uniformly, does the point have radial and/or tangential acceleration? (c) for what cases would the magnitude of either component of linear acceleration change? explain.

For a constant angular velocity, radial acceleration is zero. So, only tangential acceleration exists.B. If ω increases radial acceleration also exists.c. If tangential velocity changes, linear acceleration will change.Tangential acceleration is the rate of change of tangential velocity in the rotational motion of an object. Acts in the tangent direction at the object's moving point. The tangential velocity acts in the same direction on an object in a circular motion.Centripetal acceleration is due to changes in direction of tangential velocity, and tangential acceleration is due to changes in the magnitude of tangential velocity.Tangential acceleration acts in the tangential direction at points of circular motion. Its direction is always perpendicular to the centripetal acceleration of the rotating body.Learn more about tangential acceleration here:-https://brainly.com/question/14368661#SPJ4
