QUESTION:
Problem 17P
Pilots can be tested for the stresses of flying highspeed jets in a whirling “human centrifuge,” which takes 1.0 min to turn through 20 complete revolutions before reaching its final speed. (a) What was its angular acceleration (assumed constant), and (b) what was its final angular speed in rpm?
ANSWER:
Step 1 of 3
The following are given by the question:
Number of the revolutions,
Time takes for revolution,
Initial angular velocity,
Part (a) We know angular acceleration equation,
Here, is number of revolutions, t is the time, is initial angular velocity and is the angular acceleration.
