A) First: Frictionless surface. Draw the FBDS of each object. Derive algorithms for the acceleration of the blocks and the tension in the strings between them if the surface is frictionless in terms of the variables m, m,,0,g. Box them. Then put the values in, with units, and find numerical values to 3 sig figs. Box it. B) Repeat part A if the coefficient of kinetic friction between the block and the incline is = 0.15. Redo the FBD for the mass on the incline. C) What coefficient of kinetic friction would allow the blocks to move with a constant speed? Justify your answer.
