A pulley of radius 15 cm turns at 8 revolutions per second. What is the linear velocity of the belt driving the pulley in meters per second?
Here is the way I did this--am I correct?
v = 2pi r/T
v = 2pi (15)/8
v = 94.2/8
v = 11.8

T is not 8 ... 8 revolutions per second means sec.
also, you need to pay attention to your units ... 15 cm = .15 m
Thanks for your help on the linear velocity problem.
