Two masses m1 = .5kg and m2 = .2kg are attached by an unstretchable string over a mass-less pulley. m1 hangs over the edge not touching any surfaces. m2 sits on the surface of the table with a coefficient of friction of μ = .1. A second string attached to m2 is pulled horizontally to accelerate the masses away from the edge. If the tension of T2 is 5.6N what is the acceleration?What is T1, the string between the two masses?

Question

Two masses m1 = .5kg and m2 = .2kg are attached by an unstretchable string over a mass-less pulley. m1 hangs over the edge not touching any surfaces. m2 sits on the surface of the table with a coefficient of friction of μ = .1. A second string attached to m2 is pulled horizontally to accelerate the masses away from the edge. If the tension of T2 is 5.6N what is the acceleration?
What is T1, the string between the two masses?
