Two disks are rotating about the same axis. Disk A has a moment of inertia of 3.3 kg · m2 and an angular velocity of +7.4 rad/s. Disk B is rotating with an angular velocity of -9.3 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -2.5 rad/s. The axis of rotation for this unit is the same as that for...

Two disks are rotating about the same axis. Disk A has a moment of inertia of 4.45 kg.m2 and an angular velocity of +4.87 rad/s. Disk B is rotating with an angular velocity of -7.28 rad/s. The two disks are then linked together without the orques, so that they rotate as a single unit with an angular velocity of -3.59 rad/s. The axis of rotation for this unit is the same as that for the separate disks. What is the...

Two disks are rotating about the same axis. Disk A has a moment of inertia of 6.08 kg·m2 and an angular velocity of +3.60 rad/s. Disk B is rotating with an angular velocity of -6.84 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -4.50 rad/s. The axis of rotation for this unit is the same as that for the separate...

Figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.00 m and a mass of 20 kg and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t=1.25 s the disk has an angular velocity of 250 rad/s counterclockwise. Force F1 has a magnitude of 0.100 N. What is magnitude F2? TE

A disk of mass m, = 70.0 g and radius r , = 4.50 cm slides on a frictionless sheet of ice with velocity v, where v = 12.00 m/s, as shown in a top-down view in figure (a) below. The edge of this disk just grazes the edge of a second disk in a glancing blow. The second disk has a mass m2 = 140 g, a radius r2 = 6.00 cm, and is initially at rest. As the...
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass.
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass. The axis is perpendicular to the disk. The moment of inertial for the disk with a central axis is I MR2. Two non-rotating smaller disks, each with mass M2 and radius R/4, are glued on the original disk as shown in the figure. (a) Show that the ratio of the moments of inertia is given by I'/I = 35/16, where I' is the moment...

5. Disk A, of radius R1=10.0 cm and mass m1=5
kg is rotating about its axis at a rate of 42.0 rpm. It is brought
in contact with another disk, B, of radius R2=15.0 cm and mass m2=6
kg at rest. Quickly, both disks start to rotate together at the
same rate. Both disks rotate on their shafts on low friction
bearings.
