A belt connects a pulley of radius 8 centimeters to a pulley of radius 6 centimeters. Each point on the belt is traveling at 24 centimeters per second. Find the angular velocity of each pulley

v=r*angular velocity
so one angular velocity is 24 /6 =4 (1/s()pulley r=6cm)
and the other = 24/8 =3 (1/s) (pulley 8 cm)

K. Both are traveling the same... The smaller pulley will still be traveling that 24 centimeters per second. The larger pulley, though larger, will have less RPM. so it will still travel on the outer surface at that speed. It could be considered a trick question, but that belt determines the outer speed of the pulleys. Both are equal...God bless. Earl
