Constants| Periodic Table A mass is performing simple harmonic motion. You may assume that there are no significant frictional forces in this problem (the motion is undamped). The maximum speed of the mass during the motion is 4.6 m/s. The amplitude of the motion is 23 cm Part C Part A What is the maximum acceleration of the mass during this motion? What is w, the angular frequency of this motion? Express your answer using two significant figures Express your...

Constants| Periodic Table Part A In the figure the lower disk, of mass 430 g and radius 3.1 cm, is rotating at 180 rpm on a frictionless shaft of negligible radius. The upper disk, of mass 270 g and radius 2.5 cm, is initially not rotating. It drops freely down onto the lower disk, and frictional forces bring the two disks to a common rotational speed. (Figure 1) Find the final common frequency in rpm. Express your answer using two...
