Water is drawn from a well in a bucket tied to the end of a rope whose other end wraps around a solid cylinder of mass 50 kg and diameter 25 cm. as this cylinder is turned with a crank, the rope raises the bucket. the mass of a bucket of water is 20 kg. someone cranks the bucket up and then lets go of the crank, and the bucket of water falls down to the bottom of the well. without friction or air resistance, what is the angular acceleration of the 50-kg cylinder?

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
