9.64 .. The motor of a table saw is rotating at 3450 rev>min. Apulley attached to the motor shaft drives a second pulley of halfthe diameter by means of a V-belt. A circular saw blade of diameter0.208 m is mounted on the same rotating shaft as the secondpulley. (a) The operator is careless and the blade catches andthrows back a small piece of wood. This piece of wood moveswith linear speed equal to the tangential speed of the rim of theblade. What is this speed? (b) Calculate the radial acceleration ofpoints on the outer edge of the blade to see why sawdust doesn’tstick to its teeth
