In a train crash, a train of mass 1.85 x 104 kg collides with a stationary train of mass 2.20 x 104 kg at a speed of u = 20.0 ms-1. Filling the crash, they connect and move at the same speed. There is no friction. The train driver blows a whistle which is open at one end and closed at the other. It has a length of 0.480m . The speed of sound in air is 343 ms-1. 1. Draw a diagram of the standing wave pattern of the air pressure in the whistle for its fundamental resonant frequency. Label the open and closed ends of the whistle. 2. calculate the frequency of the sound made by the whistles fundamental resonance.

In a train crash, a train of mass 1.85 x 104 kg collides with a stationary train of mass 2.20 x 104 kg at a speed of u = 20.0 ms-1. Filling the crash, they connect and move at the same speed. There is no friction.
The train driver blows a whistle which is open at one end and closed at the other. It has a length of 0.480m . The speed of sound in air is 343 ms-1.
1. Draw a diagram of the standing wave pattern of the air pressure in the whistle for its fundamental resonant frequency. Label the open and closed ends of the whistle.
2. calculate the frequency of the sound made by the whistles fundamental resonance.
