Evaluate their acceleraton and the tension in the string

Reference no: EM13118468

A 4.8kg aluminum block and a 9kg copper block are connected by a light string over a frictionless pulley. They sit on a steel surface, where theta= 38.5. The coefficient of static friction of copper on steel is .53. The coefficient of kinetic friction of copper on steel is .36. The coefficient of static friction of aluminum on steel is .61. Coefficient of kinetic friction of aluminum on steel is .47. When they are relaeased from rest will they start to move? If so determine their acceleraton and the tension in the string. If not determine the sum of the magnitudes of the forces of friction acting on the blocks.
