Question

what is the average angular acceleration of a blu-ray disc as it plays an 6.0-h set of movies? (assume the disk is scanned starting at its inner radius moving outward. express your answer to two significant figures.)

Answer 1

The average angular acceleration of a Blu-ray disc is 0.089 rad/s².

Angular acceleration refers to the time price of exchange of angular speed. As there are types of angular velocity, namely spin angular velocity and orbital angular velocity, Angular speed is the rate of change of angular displacement and angular acceleration is the rate of trade of angular pace.

Angular Acceleration is described as the time rate of change of angular velocity. it is usually expressed in radians in keeping with second in line with second. as a result, α = d ω d t. Angular acceleration is also known as rotational acceleration.

t = time duration = 6 h = 6 x 3600 sec

α = angular acceleration = (Wmax - Wmin )/t = (315 - 121)/(6 x 3600 ) = 0.089 rad/s²
