Question

A centrifuge at a museum is used to separate seeds of different sizes. The average rotational acceleration of the centrifuge according to a sign is 30 rad/s2rad/s2. Part A If starting at rest, what is the rotational velocity of the centrifuge after 10 ss?

Answer 1

`\omega = 300 rad/s`

Step-by-step explanation:

Given,

rotational acceleration = 30 rad/s²

initial angular speed = 0 m/s

time, t = 10 s

Final angular speed = ?

Using equation of rotation motion

`\omega = \omega_o + \alpha t`

`\omega =0+30* 10`

`\omega = 300 rad/s`

Rotational velocity after 10 s = 300 rad/s.
