Pls answer all of them correctly and I also care more about (i , j , and k). If you don't know or not sure, don't do it please. These are the values of B= 20 and C=120
1. Use M1- kg and My= kg and assume there is a friction in incline (0-300) and the kinetic friction coefficient is uk-0.30, but there is no friction between My and vertical plane. Very light weighted wires with tension force FT, pull on My blocks parallel to the surface of the ramp down with acceleration "a" when the system is released gently from rest. a. Draw a Free Body Diagram for each object on the above diagram (you should draw it on your paper) and label forces as FG, F, FT, FN to show force of gravity, force of friction, force of tension and force of normal respectively. You should use notation FG1 and FN1 for Mi and MA FGz and FN2 for Mz. Draw X and Y coordinates on the above diagram for both objects. (10 points) b. For each object write Newton's second law by using above drawn X and Y directions. (You should use the above symbols and notations, plugging numbers will receive zero credits here). (10 Points) c. Calculate the force of gravity for M, and write it as Far (5 points) d. Calculate the force of gravity for M2 and write it as Fez(5 points) e. Calculate the force of normal for Mi and write it as Fan (10 points) [. Calculate the force of friction for My and write it as Fi (10 points) g. Calculate the acceleration "a" of blocks? Is your My accelerate up or down? (10 points) h. Calculate the tension force Fr of the wires connecting two blocks? (10 points) After the system moves with calculated acceleration for some time, objects stuck on the pully and wire break down. Then M2 moves "/" vertical distance from the rest, and drops onto the vertically aligned spring of spring constant k=1200 N/m. Write initial total energy formula of Me by choosing potential energy zero point for your convenience? Clearly explain where you choose PE=0 (10 points) j. Write final total energy formula of My after object combined with the spring and spring compress *y" distance and then rest (10 points) k. Now use energy conservation to calculate "y if - C cm? (10 points)
