Problem 7: In the figure below we have three blocks of mass m₁ = 2 kg, m₂ = 4 kg, and m3 = 10 kg. m₂ and m₂ are on an inclined plane with 8 = 30° and coefficient of kinetic friction 0.2. m₁ and m₂ are connected by a rope that provides a tension T₁. m₂ and m3 are connected by rope that provides a tension T₂ and this rope goes over a frictionless pulley. (a) What is the acceleration of the system? Answer: 3.7 m/sec². (b) What is the tension T₁ on the rope connection m, and m₂? Answer: 20.6 N. (c) What is the tension T₂ on the rope connection m₂ and m3? Answer: 61.0 N. T2 0 m1 T₁ Hk m₂ Hk T2 M3
