Compute each part of given question:
Question: A string with both ends held fixed is vibrating in its third harmonic. The waves have a speed of 191 m/s and a frequency of 235 Hz. The amplitude of the standing wave at an antinodes is 0.45 cm.
Part I: Calculate the amplitude at point on the string a distance of 23 cm from the left-hand end of the string.
Part II: How much time does it take the string to go from its largest upward displacement to its largest downward displacement at this point?
Part III: Calculate the maximum transverse velocity of the string at this point.
Part IV: calculate the maximum transverse acceleration of the string at this point.
I have been stuck on this question for a long time, please help. Show steps. THANKS!
