MY NOTES ASK YOUR TEACHER Big Ben, the Parliament tower clock in London, has hour and minute hands with lengths of 2.70 m and 4.50 m and masses of 60.0 kg and 100 kg, respectively. Calculate the total angular momentum of these hands about the center point. (You may model the hands as long, thin rods rotating about one end. Assume the hour and minute hands are rotating at a constant rate of one revolution per 12 hours and 60 minutes, respectively.) magnitude (No Response) 1.2 kg . m 2 /s direction (No Response) into the clock26.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHE A 62.0-kg woman stands at the western rim of a horizontal turntable having a moment of inertia of 510 kg . m and a radius of 2.00 m. The turntable is initially at rest and is free to rotate about a frictionless, vertical axle through its center. The woman then starts walking around the rim clockwise (as viewed from above the system) at a constant speed of 1.50 m/s relative to the Earth. Consider the woman-turntable system as motion begins.(cl) In what direction and with what angular speed does the turntable rotate? magnitude {No Response) 7,1 0.365 rad/s direction {No Response) 7,) counterclockwise (e) How much chemical energy does. the woman's bodyr convert into mechanical energy of the womanturntable system as the woman sets herself and the turntable into motion? {NoRaponse} J.) 104 _ 37.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHI A uniform cylindrical turntable of radius 1.70 m and mass 31.5 kg rotates counterclockwise in a horizontal plane with an initial angular speed of 47 rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.38 kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.60 m to the east of the axis. (a) Find the final angular speed of the clay and turntable. magnitude (No Response) 11.1 rad/s direction (No Response) counterclockwise (b) Is mechanical energy of the turntable-clay system constant in this process? Yes OP NO What, if any, is the change in internal energy? (No Response) 424 J (c) Is momentum of the system constant in this process? Yes O 2 NO What, if any, is the amount of impulse imparted by the bearing? magnitude (No Response) 42.2 kg . m/s direction (No Response) northStep by Step Solution
