Suppose you discover your grandfather's collection of Caruso records from the early part of the century. These disks played at 78.0 revolutions/minute (rpm) and were 9.00in. in diameter.
What was the radial acceleration of a point on the rim of such a record as you listened to the great tenor singing?
