Answer to Question #193250 in Classical Mechanics for Lina

Question

Mass of block 1 is m1 = 3.0 kg, while the mass of block 2 is m2 = 6.0 kg. The coefficient of friction between m1 and the inclined surface is (mu)k = 0.40 . The string and pulley are massless. (a) What is the acceleration of the system? (b) What is the tension of the string? (c) Starting from rest, what is the kinetic energy of the system when m2 drops by h= 0.20 m?
