A centrifuge rotor rotating at 9500 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.93 m⋅N . If the mass of the rotor is 4.69 kg and it can be approximated as a solid cylinder of radius 0.0600 m , through how many revolutions will the rotor turn before coming to rest? How long will it take? Express your answer to three significant figures and include the appropriate units.

40. (II) Calculate the moment of inertia of the array of point objects shown in Fig. 10-53 about (a) the vertical axis, and (b) the horizontal axis. Assume m = 2.2 kg, M = 3.1 kg, and the objects are wired together by very light, rigid pieces of wire. The array is rectangular and is split through the middle by the horizontal axis. (c) About which axis would it be harder to accelerate this array? 3. (II) A centrifuge rotor...

A centrifuge accelerates uniformly from rest to 15000 rpm in 320 s . Part A Through how many revolutions did it turn in this time? Express your answer using two significant figures. I've tried 4000, 6366, and 6400; all were marked wrong, what am I missing here?
The rotor (flywheel) of a toy gyroscope has a mass of 0.165 kg. Its moment of inertia about its axis is 1.15 × 10-4 kg-m2 The mass of the frame is 0.0275 kg. The gyroscope is supported on a single pivot (see the figure below (Figure 1) with its center of mass a horizontal distance of 3.80 cm from the pivot. The gyroscope is precessing in a horizontal plane at the rate of 1 revolution in 2.50 s Part A...
Constants| Periodic Table Part A In the figure the lower disk, of mass 430 g and radius 3.1 cm, is rotating at 180 rpm on a frictionless shaft of negligible radius. The upper disk, of mass 270 g and radius 2.5 cm, is initially not rotating. It drops freely down onto the lower disk, and frictional forces bring the two disks to a common rotational speed. (Figure 1) Find the final common frequency in rpm. Express your answer using two...
