1. The problem statement, all variables and given/known data Determine a formula for the acceleration of the system shown in the figure(Figure 1) in terms of mA, mB, and the mass of the cord, mC. Assume f to be the fraction of the cord that is hanging down between mB and the pulley, and μk to be the coefficient of kinetic friction between mass mA and the table. Express your answer in terms of the variables mA, mB, mC, μk, f, and appropriate constants. 2. Relevant equations F=ma 3. The attempt at a solution I've been trying to solve this for the past hour but I can't seem too get it. I know that for mass B---(mB+f)g-Tb=(mA+mB+mC)a-- where Tb is the tension in the cord. Also for A----Ta-μk(mA*g)=mAa------ & n=mA*g--------From here on I've been stumped. Whatever approach I took to solve the problem didn't end up working. Can somebody please push me in the right direction. Also, I'm unsure if my force equations are correct, somebody please help.
