Question
It takes a time t = 0.59 s for a record to revolve on a record player once. A particular point on the record moves past the needle at a speed of vn = 1.06 m/s.
t = 0.59 s
vn = 1.06 m/s
a. What is the radius at which the needle is in contact with the record in m?
b. What is the tangential speed v2 of a point on the record that is at r2 = 0.05 m in m/s?
