Abunging Weight With A Mass Of M 0 350 Kg Is Attached By A String To A Block With Mass M 0 810 Kg As Shown In The Fi 1 (23.16 KiB) Viewed 28 times

Abunging weight, with a mass of m, 0.350 kg, is attached by a string to a block with mass m, 0.810 kg as shown in the figure below. The string goes over a pulley with a mass of M=0.350 kg. The polley can be modeled as a hollow cylinder with an inner radius of 0.0200 m, and an outer radius of R, = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the blockslides on the table, and the coefficient of inetic friction between the block and the table is 0.250. At the instant shown, the block is moving with a velocity of -0.620 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 RR () ing energy methods, find the speed of the block (in mus) ter it has moved a distince of 0.700 m away from the initial position shown m/ (6) What is the angular speed of the pulley (nrad/s) after the black has moved this distance? rad/
