Question 5:
Part 1: A LP (long play) vinyl record rotates
on a turntable at typical speed of 33.3 RPM:
1. What is the angular velocity in rad/s?
2. What is the period of the motion in seconds?
Part 2: Imagine that the recording on the
disk is a ‘click track’, consisting a series of sharp ‘clicks’ each
separated in time by 0.29 s:
1. What is the distance of the arc between successive clicks at
a radius of 22.93 cm in cm?
2. What is the distance of the arc between successive clicks at
a smaller radius of 8.5 cm in cm?
3. What is the difference in linear speeds for
the needle travelling over the surface of the record for these
two cases in m/s?
