Lоng Questiоn B (Tоtаl 20 Points) (Course Outcome 5 - Rigid Body Kinetics) Consider the Disc-Block system joined together with а mаssless and rigid bar of length l on top of a rough incline of. The mass of the disc is 3M and it has a radius of R. The mass of the block is M. it's moment of inertia is and the height and width of the block are h and w respectively. There is a spring of stiffness k attached to the bottom of the incline. The disc is rolling without slip while the block slips down the incline. The system starts at rest and a distance of D (measure along the incline) from the spring and the system's motion can be broken down into two phases. Phase 1 is before the block makes contact with the spring. Phase 2 is after the block makes contact with the spring with the spring being at a height of L from the center of mass of the block. You are asked to find the equation of motion of the system. Answer all the questions below. Write down your work and submit it accordingly for partial credit.
