Hii can you answer these three questions with explaination please ???

11. In the diagram at right, m2 has a mass of 20.0 kg. There is friction on the incline. Static friction can exert a maximum force of 30.0 N on m2. This friction can act up or down the incline, depending on the value of mi. a) If m1 isheavy enough, m2 will start to accelerate up the incline. What is the maximum value m1 can have without m2 sliding up the incline? ( b) If m1 is light enough, m2 will start to accelerate down the incline. What is the minimum value m1 can have without m2 sliding down the incline. (static friction is not in the same direction as part a)) (use Mr. Walsh's simulation to check your work, check your FDB and to get a better understanding of the problem) 12. If mass #1 = 2 kg, mass #2 = 4 kg, and mass # 3 = 6 kg, find the acceleration of the three masses, and the tension in each string. The pulleys are frictionless, but the coefficient of kinetic friction between the plane and block 2 is 0.400. 2 200 40 13. If both masses above equal 3 kg, find the acceleration of the two masses, and the tension in the string. The 40 incline is frictionless, but the 20 incline has a coefficient of kinetic friction of 0.100
