Angular acceleration in the spin cycle of a clothes washer, the drum turns at
635 rev/min. if the lid of the washer is opened, the motor is turned off. if the drum
requires 8.0 s to slow to a stop, what is the angular acceleration of the drum?

Respuesta :

The angular acceleration is 531. 98 rad/s

How to calculate angular acceleration

Using the formula:

Angular acceleration  = change in angular velocity / change in time taken

Angular velocity = 635 rev/ min, covert to rad/ sec

The frequency in radians per second is equal to the revolutions per minute multiplied by 0.10472

Then angular velocity in rad/sec = 635 * 0.10472 = 66. 4972 rad/sec

time = 8. 0s

Substitute into the formula

Angular acceleration = 66. 4972 / 8. 0

Angular acceleration = 531. 98 rad/s²

Thus, the angular acceleration is 531. 98 rad/s²
