Figure 49 the Figure Shows Two Objects of Masses M₁

question 22

Essay

Figure 4.9 The figure shows two objects of masses m₁ and m₂ placed on two inclined surfaces of different angles, è₁ and è₂. The connection between the masses is a taut, massless string running over a massless and frictionless pulley.
-In Fig. 4.9, the masses are m₁= 10 kg and m₂ = 20 kg, and the incline angles are è₁ = 30° and è₂ = 50°. What are the magnitude and the direction of acceleration of the system and the tension in the string if the coefficient of friction for the surface under m₁ is ì₁ = 0.30 and under m₂ it is ì₂ = 0.40.
