If the fundamental frequency of a cylinder is 310 Hz, and the speed of sound is 343 m/s, determine the length of the cylinder (in m) for each of the following cases. a. the cylinder is closed at one end
b. the cylinder is open at both ends.

a)  

b)  

Explanation:

From the question we are told that:

Frequency

Speed

a)

Generally the equation for Frequency is mathematically given by

The cylinder is closed at one end

b)

Generally the equation for Frequency is mathematically given by

the cylinder is open at both ends.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
