Consider an object on a rotating disk a distance ? from its center, held in place on thedisk by static friction. Which of the following statements is true concerning this object? Multiple statements can be true. a.If the angular speed is constant, the object must have constant tangential velocity.b. If the angular speed is constant, the object is not accelerating.C. The object has a tangential acceleration only if the disk has an angular acceleration.d. If the disk has an angular acceleration, the object has both a centripetal acceleration and atangential acceleration.
