Question

Электромотор, вращаясь равноускоренно, сделал 200 оборотов за 10 с от начала движения. Найти: угловое ускорение

Answer 1

Ответ будет 10:200=0,05

Answer 2

Calculation of Angular Acceleration

To find the angular acceleration of the electric motor, we can use the formula:

Angular acceleration (α) = (Change in angular velocity) / (Change in time)

Given that the electric motor made 200 revolutions in 10 seconds, we can calculate the angular velocity using the formula:

Angular velocity (ω) = (Number of revolutions) / (Time)

Let's calculate the angular velocity first:

Angular velocity (ω) = 200 revolutions / 10 seconds = 20 revolutions per second.

Now, we can calculate the angular acceleration:

Angular acceleration (α) = (Change in angular velocity) / (Change in time) = (20 revolutions per second) / (10 seconds) = 2 revolutions per second squared.

Therefore, the angular acceleration of the electric motor is 2 revolutions per second squared.
