A centrifuge in a medical laboratory rotates at a

science physics

Answer 1

Answer #1

wi = 2600 rev/min = 3600*2pi/60 rad/s = 376.8 rad/s

wf = 0

θ = 50 turns = 50*2pi = 100pi = 314 radians

From 3rd equation of motion

wf^2 = wi^2 + 2αθ

0 = 376.8^2 + 2α*314

=> α = -226.08 rad/s^2

Hence the magntiude of angular acceleration is 226.08 rad/s^2

A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.8 s before coming to rest. If its initial angular speed was 3810 rpm , what is the magnitude of its angular deceleration? _____5.88 rev/s^2 (Correct) How many...
