Constants A string is wrapped around a uniform solid cylinder of radius r = 0.6 m, as shown in (Figure 1). The cylinder can rotate freely about its axis. The loose end of the string is attached to a block. The block and cylinder each have mass m = 8.5 kg Part A Find the magnitude a of the angular acceleration of the cylinder as the block descends. a = Figure 1 of 1> Submit Request Answer Provide Feedback Next >

The spool has a mass of 90 kg and a radius of gyration ka = 0.3 m.

Previous Problem List A force F = 29 N i acts on an object at a point (xo, Yo) = (4.6 m, 4.7 m) as shown in the figure. y Next Yo F F X What is the magnitude of the torque generated by this force about the origin? What is the magnitude of the torque generated by this force about the point (x, y) = (2.1 m, 2.2 m)? Suppose the object is free to rotate about the z axis. If the object has a moment of inertia | = 33.0 kg*m² for rotation about the z axis, what is the magnitude of the angular acceleration of the object due to the application of the force F?
