A 8 kg disk with a radius of 1 meters has several forces applied to it as shown in the sketch. F1 is 41 N and is applied at the edge of the disk, F2 is 7 N is applied at 1/4 the radius from the center of the disk, F3 is 5 N is applied at 3/4 the radius from the center, F4is 29 N is applied at the edge of the disk, and, lastly, F5 is 16 N and is applied at the edge of the disk at an angle of 23 degrees. If the moment of inertia about the center for the disk is I = 1/2 M R2, and the disk is initially spinning at 36 rad/s counter-clockwise its center, how long, in seconds, does it take the disk to be spinning at 10 rad/s counter-clockwise about its center?

A 6 kg disk with a hole in its center has a c value about its
center of 0.57 has an outer radius of 3.5 meters. A force of 9
Newtons is applied in the -x direction at the edge of the disk
directly to the right of its center. Another force of 34 Newtons is
applied directly above the center in the -x direction halfway
between the center and edge of the disk. Lastly, a force of 15
Newtons...

A force of 5 Newtons is applied in the -x direction at the edge of the disk directly to the right of its center. Another force of 28 Newtons is applied directly above the center in the -x direction halfway between the center and edge of the disk. Lastly, a force of 15 Newtons...
A uniform disk with mass m = 8.55 kg and radius R = 1.35 m lies in the xy plane and centered at the origin. Three forces act on the disk in the +y-direction (see figure below): (1) a force F1 = 335 N at the edge of the disk on the +x-axis, (2) a force F2 = 335 N at the edge of the disk on the ?y-axis, and (3) a force F3 = 335 N at the edge...
8) A disk is initially spinning about its center at 21 rad/s counter-clockwise and a constant angular acceleration of 2.6 rad/s2 is applied to it clockwise. After 3.2 seconds how fast is a piece of dust moving, in m/s, which is 0.64 meters from the center of the disk?
A solid disk with a c value of 1/2, mass of 3 kg, and radius of 1.5 meters lies on a horizontally (so the normal force and weight can be ignored). A force of 9 Newtons is applied 0.22 meters directly to the right of the center in the +x direction, a force of 24 Newtons is applied at 0.81 meters directly below of the center in the +x direction and a force of 8 Newtons is applied at the...

A force of 7 Newtons is applied 0.34 meters directly to the right of center in the +x direction, a force of 23 Newtons is applied 0.77 meters directly below of center in the +x direction, and a force of 7 Newtons is applied at the edge of the disk...
Question 7 8 pts A disk is rotating at 21 rad/s counter-clockwise about its center and a constant angular acceleration of 4 rad/s? is applied to it clockwise. After 0.69 seconds, what is its rotational kinetic energy about its center if c 1/2, the mass of the disk is 4 kg, and its radius is 0.74 meters? Answer in Joules.
A uniform disk with mass m = 9.07 kg and radius R = 1.36 m lies in the x-y plane and centered at the origin. Three forces act in the +y-direction on the disk: 1) a force 313 N at the edge of the disk on the +x-axis, 2) a force 313 N at the edge of the disk on the –y-axis, and 3) a force 313 N acts at the edge of the disk at an angle θ =...
A disk with radius 0.6 meters and mass 31 kg is spinning about its own center with an angular velocity of 88ed A solid sphere (/ mR2) with a radius of 0.18 meters which is spinning with an angular velocity of -18 ed (the negative sign indicates the opposite 6. rad sec direction), is gently lowered onto the disk a sticks to the disk. The two rotate together (about their mutual center of mass) at an angular velocity of 33...
