A block of mass m = 2.70 kg is hanging from a massless cord that is wrapped around a pulley (mass = 4.00 kg) asshown in the figure. The cord does not slip relative to the pulley as the block falls. Find the magnitude of the tension inthe cord. (moment of inertia of the pulley = ½Mr²)
Two blocks are attached by strings of negligible mass to a pulley with two radii R1=0.29 m and R2=0.69 m. The strings are wrapped around their respective radii so that the blocks can move either up or down. The pulley has a moment of inertia about its center I=0.221 kg⋅m2, and is supported by a bearing with negligible friction. If block 1 has a mass of 2.9 kg and block 2 has a mass of 0.42 kg, what is the magnitude of the angular acceleration of the pulley?
