The flywheel turns clockwise with a constant speed of 580 rev/min, and the connecting rod AB slides through the pivoted collar at C. For the position θ = 48°, determine the angular velocity ωAB (positive if counterclockwise, negative if clockwise) of AB by using the relative-velocity relations. (Suggestion: Choose a point D on AB coincident with C as a reference point whose direction of velocity is known.)

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
