Which of the following statements are true? (select all that apply.) all parts of a wheel rotating about a fixed axis must have the same angular speed. all parts of a wheel rotating about a fixed axis must have the same angular acceleration. all parts of a wheel rotating about a fixed axis must have the same centripetal acceleration. angular speed and linear velocity have the same dimensions.

All parts of a wheel rotating about a fixed axis must have the same angular speed.

All parts of a wheel rotating about a fixed axis must have the same angular acceleration.

Explanation:

In a rigid body in rotation (a rotating wheel) with respect to a fixed axis, each particle on the body turns around the same angle in a certain time interval, having the same angular speed and the same angular acceleration. Otherwise, the wheel will deform, therefore it would not be in equilibrium

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
