The ball (the figure) slides on the lane with initial speed vcom.O friction between the ball and the lane is 0.29. The kinetic frictional force 7k acting on the ball causes a linear acceleration of the ball while producing a torque that causes an angular acceleration of = 8.4 m/s and initial angular speed wo 0.

- Newton's second law for linear motion is mà The equivalent form for rotational motion is - là, where is torque, I stands for the moment of inertia, and is the angular acceleration. The effectiveness of the applied torque is determined by: O The amount of Force applied The distance of the applied force from the axis of rotation. O The angle between the applied force vector Fand the vector distance from the axis of rotation to the applied point of the force O All of the above"The edge of the disk has a constant tangential speed. This means that the tangential speed of the block will increase the farther away it is placed from the center of the disk." I don't understnd why this is trueNeeds Complete typed solution with 100 % accuracy.
