Ac = v^2/R
980 = v^2/2
v = 44.3 meters /second
v = omega * R
omega = 44.3/2 = 22.2 radians / second
An apparatus is designed to study insects at an accelera�tion of magnitude 980 m/s 2 ( = 100 g). 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 980 m/s 2
?
(b) What is the angular speed of the insect?
