So the initial velocity is 15 m/s, the final velocity is 0 since it's at a complete stop and time is 10 seconds. Therefore:
Therefore, the acceleration is -1.5 m/s^2. The reason it's negative is due to the fact that the vector is going against it's original movement since it's decelerating.
Frequency decreases whilst wavelength increases and the opposite also occurs
Answer:
The first harmonics are the fundamental, the first overtone, and the second overtone,
For a string fixed at both ends you have:
N-A-N F/2
N-A-N-A-N F
N-A-N-A-N-A-N 3 F/2 each harmonic increases by F/2
Where N are the anti-nodes and A the antinodes
N-A-N-A-N represents 1 wavelength for string fixed at both ends
So 1 wavelength is 64 cm
280 m/s = F * .64 m and F = 437.5 Hz (second harmonic)
First harmonic = F/2 = 218.75 / sec
Third harmonic = 3 F / 2 = 656.25 /sec
