Question

An ant and a beetle are riding a spinning record on a record player. The ant stands on the outside edge of the record while the beetle stands on the record's label. The ant is four times as far from the center of rotation as the beetle. What is the ratio of the ant's centripetal acceleration to the beetle's?

Please explain :) Thank you!

Answer 1

Ac = w^2 R
w the same
R2 = 4 R1
so four times
