An Annular ring with a mass of 2.93 kg, an innner rdius of 15.8cm, and an outer rdius of 34.2 cm is free to rotate about the z-axis which coincides with its axis of cylindrical symmetry. Initially at rest, a constant = torque, \tau (55.5mN·m)k is applies through 5.91 revolutions. By how much in joules, does the kinetic energey of the ring increase?

The thin, homogeneous, circular disk B rotates about a fixed, frictionless axis O, located at its centre, with an angular velocity of ω = 2.5 rad/s (clockwise). Object Alands on the disk at the indicated position where θ = 53o, with an absolute velocity of 1.8 m/s at an angle of ψ = 25o as shown. Determine the angular speed of disk Bimmediately after object A has landed and rotates with B. Take the mass of the object as mA = 5 kg and the radius of gyration about an axis passing perpendicularly through its centre of gravity as kG = 0.18 m. The mass of disk B is mB = 14 kg and its radius is R = 1.7 m. Initially object A is a distance of r = 1.1 m from the axis of rotation.
