Question

An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 8690 rpm while it is being read, and then is allowed to come to rest over 0.569 s, what is the magnitude of the average angular acceleration of the disk?

Step 1

Given: Initial velocity = 8690 rpm 1 revolution = 1 rotation 1 minute = 60 seconds Initial velocity = 8690 rpm * (1 revolution / 1 rotation) * (1 minute / 60 seconds) Initial velocity = 8690 / 60 revolutions per second Initial velocity = 144.833 revolutions per Show more…
