Question
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.
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.Explanation / Answer
1. (a) If radial acceleration is the same as centripetal acceleration, then: let @=centripetal acceleration;
@=v^2/r
@r=v^2
squareroot(@r)=v
v = squareroot(990m/s2 X 1m) = squareroot(990) (m/s)
(b) w = angular speed ; v=wr
w = v/r = squareroot(990) / 1m = squareroot(990) (rad/s)
