At a point near the rim of the disk, it will have a<span> non-zero radial acceleration and a zero tangential acceleration. Also known as centripetal acceleration, radial acceleration takes place along the radius of the disk. On the other hand, the tangential acceleration is along the path of disk's motion.</span>
ball drops 45m under g=10m/s/s
45=1/2x10xt^2 ... application of kinematic equaion from rest

24.0 m in 3 secs => 8m/s no air resistance
A path of inferences guided to be cherry picked as for which ones were reasonable and which ones had no ability in the real world to sustain in scientific law
