Question

My grandma had an antique record player that could play records at an angular velocity of  (RPM’s). The largest records from that era had a radius is . A point A is  from the center, while point B is  from the center. If the record is spinning at ’s. Which of the following is true? [more than one answer may be correct]
Both point A and point B have an angular velocity of 8.17 rad/s .

Point B has a greater angular velocity than point A.

Both point A and point B have the same linear (tangential) velocity.

All points on the record must have the same linear velocity.

Point B. has a greater linear (tangential) velocity than point A.
