Question
An apparatus is designed to study insects at an acceleration of magnitude 94g (here g does not mean "gram", but rather g=9.8 m/s2). The apparatus consists of a 4.4 m rod with insect containers at either end. The rod rotates aobut an axis perpendicular to the rod and at its center (see the image for problem 14 on page 185 of your physics textbook.) What is the angular speed of the insects?
CHEGG,
Please use simple formulas (i.e. ac = (Vt2)/R = wVt = w2R and F = (mV2)/r and [arc length] = [angle in radians]/[t] etc.), and please show ALL your work. Thank you!
Explanation / Answer
w = v/r
w = sqrt(ac/r)
w = sqrt(94*9.8 / 2.2)
w = 20.46 rad/s
