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 disk is initially rotating (about its center) at 48 rad/s counter-clockwise. After a constant angular acceleration is applied to it for 2.2 seconds, it is rotating at 9 rad/s counter-clockwise. How many revolutions does the disk make in that time
A disk is originally spinning about its center at 6 rad/s counter-clockwise. A constant angular acceleration (about its center) is applied to it and it stops spinning after 6 seconds. How many revolutions are made before it is stopped?
A disk is originally spinning about its center at 4.8 rad/s clockwise. It makes 3.6 revolutions before it is stopped. If under a constant angular acceleration, how long does it take to stop in seconds?
A disk is initialy at rest and a constant angular acceleration of 5 rad/s? is applied to it counter-clockwise (about its center). After 5.8 seconds, the constant angular acceleration value switches to 10 rad/s? clockwise. How many revolutions, in total, are made before the disk is stopped again?
A 10 kg disk with a hole in its center has a c value about its center of 0.56 has an outer radius of 3.6 meters. 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 hollow disk is rotating about its center at 5 rad/s. Friction is acting on the disk at the axis of rotation producing an angular acceleration of 1 rad/s. How many revolutions will the disk rotate before coming to a stop?
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 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...
A spinning disk is rotating at a rate of 2 rad/s in the clockwise direction as shown in the figure. What is the direction of the angular velocity vector? If the disk is slowing down at a rate of 4 rad/s2, what is the direction of the angular acceleration vector? Find the wheel's angular velocity after 2 s. Find the angle through which the wheel has turned after 2 s in radians. Find the magnitude of the velocity (speed) of...
