Answer:
The length of open-open pipe needed is 6.23 m
The length of open-close pipe needed is 3.11 m
Explanation:
Fundamental frequency for standing wave mode of an open- open pipe is given by
where v is the velocity and L is the length
The length of open-open pipe needed is
Fundamental frequency for standing wave mode of an open- close pipe is given by
The length of open-close pipe needed is
As we know from the equation of kinematics
here it starts from rest
final angular speed will become 90 rad/s in time interval of t = 10 s
now we will have
So it will stop after 50 seconds of constant deceleration.
