Two friction disks A and Bare to be brought into contact without slipping when the angular velocity of disk A is 380 rpm counterclockwise. Disk A starts from rest at time t= 0 and is given a constant angular acceleration of magnitude a. Disk B starts from rest at time t= 2 s and is given a constant clockwise angular acceleration, also of magnitude a.

part a is correct

Two friction disks A and Bare to be brought into contact without slipping when the angular velocity of disk A is 380 rpm counterclockwise. Disk A starts from rest at time t= 0 and is given a constant angular acceleration of magnitude a. Disk B starts from rest at time t= 2s and is given a constant clockwise angular acceleration, also of magnitude a. A 150 mm B 200 mm Determine the required angular acceleration magnitude a. (You must provide an answer before moving to the next part.) The required angular acceleration magnitude a is 4.98 rad/s2.
