A 4kg 15 4kg 4kg Three 4-kg packages A, B, and C are placed on a conveyor belt that is at rest. Between the belt and both packages A and C the coefficients of friction are μ = 0.30 and μ=0.20; the coefficients are μ. = 0.10 and between package B and the belt -0.08. The packages are placed on the belt so that they are in contact with each other and at rest. Determine which, if any, of the packages will move and the friction force acting on each package.
