Final answer:
To find the angular speed of the pulley, use the formula: angular speed = 2π × number of rotations / time taken. Calculate the value using the given information.
Step-by-step explanation:
The angular speed of a pulley can be found using the formula: angular speed = 2π × number of rotations / time taken. In this case, the pulley rotates [insert number of rotations] times in [insert time in seconds]. Substituting these values into the formula, we can calculate the angular speed.
angular speed = 2π × number of rotations / time taken
angular speed = 2π × [insert number of rotations] / [insert time in seconds]
angular speed = [insert calculated value] rad/s
