2. A hanging weight, with a mass of m1 = 0.370 kg, is attached by a string to a block with mass m2 0.820 kg as shown in the figure below. The string goes over a pulley with a mass of M= 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is uk = 0.250. At the instant shown, the block is moving with a velocity of vi = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. R2 R a.

Two blocks are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below. 1721 Mo i The masses of the blocks are m₁ = 16.0 kg and m₂ = 11.5 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.100 m. Block m₂ is initially on the floor, and block m₁ is initially 4.20 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the rope is small enough to be ignored, and the rope does not slip on the pulley, nor does it stretch.

It is connected by a lightweight cord, which passes over a frictionless pulley (M = 10 kg, R=10 cm), to a second box of mass m2 = 20 kg, which hangs freely as shown. The contact between mass m, and the incline is smooth. The system is released from rest and accelerates. at 0 m2 Using rotational dynamics, determine the tension T2 in the vertical portion of the cord.
