A wheel is rotating in a counterclockwise direction about its center. Then suppose the rotation rate slows to zero and then speeds up to an even greater value in the opposite direction. For an object attached to the rim of the wheel: (the equation for centripetal acceleration aC = vt2/r, where vt = tangential velocity and r is the wheel radius)
What happens to the direction of the centripetal acceleration vector (what’s the overall change in the direction)?
