A rotating furnace has been developed recently to give a rough para-
bolic curve to rolten glass. This makes the manufacture of very large
telescope mirrors easier and more economical than ever before. The
largest mirror made in this furnace to date has a radius of 4.2 m. While
in the furnace, the centripetal acceleration of the molten glass for this
mirror was 2.13 m/s? What was the tangential speed at the edge of the
molten glass?
