The rigid body shown in this diagram is moving such that the velocities of points A and B are the same. The magnitude of the velocity of point A is 25m/s and the distance between points A and B is 10m.
Determine the magnitude of the angular velocity of the rigid body.
Express your answer in rad/s and give you answer to 4

At the instant shown, theta = 45 degrees, and the magnitude of the velocity of point G is v(G) = 16m/s and the angular speed of the disk is 7 rad/s. Point G is the mass center of the disk. The Radius of the disk if R = 0.5m. Determine the magnitude of the velocity of point C at the instant shown. The unit vector i, j, and are t

Need help with the following physics problems:
1. About medio-lateral axes, the moment of inertia of a person's upper arm (shoulder-elbow segment) was found to be 0.06 kg.m^2 for rotation about the shoulder joint, and 0.08 kg.m^2 for rotation about the elbow joint. Why are these numbers different?
2. A diver's body, whil

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 fo

A diver can change her rate of rotation in the aair by "tucking" her head in and bending her knees. Let's assume that when she is stretched out straight she is rotating at 1 revolution per second. Now she goes into the "tuck and bend", effectively shortening the length of her body by half. What will her rate of rotation be now?

See attachment please.
Need FBD for each case.
The 0.2 kg ball ( ball is sliding not rotating) and the supporting cord are revolving about the vertical axis on the fixed smooth conical surface with an angular velocity of W = 4 radians/sec. The green ball is held in position b = .3 m by the tension T in the yellow cord.
If b

A wheel accelerates with a constant angular acceleration of 4.5 rad/s^2. If the initial angular velocity is 1.0 rad/s, what is the angle through which the wheel rotates in 2.0 s?
Please provide detailed explanation.
