This is a multi-part question. Once an answer is submitted, you will be unable to return to this part As steam is slowly injected into a turbine, the angular acceleration of the rotor is observed to increase linearly with the time t Know that the rotor starts from rest at t = 0 and that after 10 s the rotor has completed 20 revolutions.

Determine the angular velocity at t20 s. (You must provide an answer before moving on to the next part)

The angular velocity is [ ] rpm.
