Disk A has a mass of 8 kg and an initial angular velocity of 360 rpm clockwise; disk B has a mass of 3.5 kg and is initially at rest. The disks are brought together by applying a horizontal force of magnitude 20 N to the axle of disk A. Assume that μk = 0.15 between the disks. Neglect bearing friction.

Required:
Determine:
a. the angular acceleration of each disk.
b. the final angular velocity of each disk.

a. the angular acceleration of each disk;

For disk A, the angular acceleration is 9.36 rad/s²

For disk B, the angular acceleration is 28.57 rad/s²

b. the final angular velocity of each disk;

For disk A, the final angular velocity is 250.57 rpm

For disk A, the final angular velocity is 334.00 rpm

Explanation:

While slipping occurs, and upward friction force F is applied to disk A, and downward friction force F to disk B.

Assumption;

Radius of disk A is 80 mm

Radius of disk B is 60 mm.

Pls find the explanation of the question in the attached files as typing it here may be difficult due to the equations and diagrams involved.

the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
