Homework Statement

ok this is a little silly.

An apparatus of the figure below is designed to study insects at an acceleration of magnitude 910 m/s2 (= 93g). The apparatus consists of a 2.0-m rod with insect containers at either end. The rod rotates about an axis perpendicular to the rod and at its center.

(a) How fast does an insect move when it experiences a radial acceleration of 910 m/s2?
(b) What is the angular speed of the insect?

Homework Equations

The Attempt at a Solution

ok this one is a little silly. I can solve it, the answers are 30.2 for both. The problem is I can't solve it AGAIN, I originally did the problem 3 days ago and am now trying to make sure I can still do them all for my upcoming test

Hint: Two formulae for centripetal acceleration; one using tangential velocity and the other angular velocity.
