A turbine is spinning at 3600rpm . Friction in the bearings is so low that it takes 11min to coast to a stop. How many revolutions does the turbine make while stopping?
answer: 3600/2 * 11
sorry guys my bad ... the answer is correct

Please show steps. Thank you!
To find the number of revolutions the turbine makes while stopping, we can first calculate the time taken for each revolution.
Given that the turbine is initially spinning at 3600 rpm (revolutions per minute), we can convert this to revolutions per second by dividing by 60:
3600 rpm / 60 = 60 revolutions per second
We can now use the time taken to coast to a stop, which is given as 11 minutes, or 11 * 60 = 660 seconds.
To find the number of revolutions, we multiply the number of revolutions per second by the time taken:
60 revolutions per second * 660 seconds = 39,600 revolutions
Therefore, the turbine makes 39,600 revolutions while stopping.
