It takes a time t = 0.68 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 = 1.01 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?
