An old-fashioned (vinyl) record rotates at a constant rate of 33 rpm.
(a) What is its angular speed in rad/s?
rad/s
(b) If the record has a radius of 9 cm, what is the linear speed of
a point on its edge?
m/s
Given data
constant rate =33rpm
angular speed(w)= 33(2pie/60)
=33(2)(3.14)/60
=3.454 rad/sec
(b) liner speed v=rw
r=0.09m
v=0.09*3.454
=0.31086m/s
