Two points are located on a rigid wheel that is rotating withdecreasing angular velocity about a fixed axis. point a islocated on the rim of the wheel and point b is halfway between therim and the axis. which one of the following statements concerningthis situation is true?
both points have the same centripetal acceleration.
both points have the same tangential acceleration.
the angular velocity at point a is greater than that of pointb.
both points have the same instantaneous angular velocity.
each second, point a turns through a greater angle than pointb.
