Learning Goal: To apply the principle of angular impulse and momentum to describe a particle's motion The moment of a force about a point O, fixed in an inertial coordinate system, Mo, and the angular momentum about the same point, Ho, are related as follows: Figure 1 of 2 ✓ Correct ▾ Part C Previous Answers While the centrifugal governor's two spheres are rotating with the angular momentum found in Part B, a moment with magnitude M= 0.420f N-m is applied to the central shaft for t= 1.95 s in the direction of rotation. (Figure 2) What is H₂, the angular momentum of the two spheres after the moment has been applied? Express your answer numerically to three significant figures with the appropriate units.
