A 10.00 kg horizontal rod ABD (length = 0.900 m), pin-connected at B, is initially at rest and is subjected to a counterclockwise couple C. At the same instant, ball S (mass = 2.50 kg) is at rest hanging vertically from the ceiling. When rod ABD becomes vertical, its end D hits ball S. Note that couple C is applied initially when the rod is horizontal until just before it hits ball S. If the angular velocity of the rod just before end D of bar ABD hits ball S is 7.50 rad/s counterclockwise and the coefficient of restitution between the rod and the ball is 0.650, answer the following questions: A C 1600₂ SD 1. Which of the following is closest to the magnitude of couple C? 2. Which of the following is the most ideally constructed momentum-impulse diagram of the system of rod ABD and ball S?

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2.  I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…
