Question
Expanded.4 deals with the conservation of momentum principle. Using the conservation of momentum principle to solve this problem is mandatory. Solution using other approaches will be automatically considered false. For the problem related to Expanded.4, sketches of the system showing: • the respective initial and final velocity and position coordinates and the frame of reference considered • the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. A B F 300 mm 600 mm Knowing the angular velocity of rotation of the bob, 4-kg, is 3 rad/s when the length of the rope is 600mm and the angle is 44°, what is the angular velocity of the rope if the length of the rope becomes 300mm while the angle reduces of 6°?
