A simple friction drive consists of two disks A and B. Initially, disk B has a clockwise angular velocity of 590 rpm, and disk A is at rest. Disk B is known to stop in 69 seconds, decelerating constantly. However, instead of waiting for both disks to be at rest before bringing them into contact, disk A is given a constant angular acceleration of 3.5 rad/s2 counterclockwise. a) Determine the time, in seconds, in which both disks can be brought into contact without slipping.
