An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s1045 rad/s ). if a particular disk is spun at 264.9 rad/s264.9 rad/s while it is being read, and then is allowed to come to rest over 0.368 seconds0.368 seconds , what is the magnitude of the average angular acceleration of the disk?

719.84 rad/s²

Explanation:

Given that:

(Has to come to rest)

t = 0.368 seconds

Thus, the expression for angular expression is:-

Applying the values in the above equation as:-

Magnitude of the average angular acceleration = 719.84 rad/s²

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

its a 5.5 n
