9. Two identical blocks of are placed on top of a rotating disk with a radius of r. The firstblock is a distance of r from the pivot point and the second is placed at. If the disk hasan angular acceleration of 1.125 radspeed is 10radS$2one of the two blocks slides off when the angular(you can consider this to be time t = 0 s. How much time will passbefore the second block slides off the disk too?
