The first five harmonics for a vibrating string are shown in Figure24.13.a. For each harmonic, identify the number of wavelengths represented. b.For each harmonic, identify the number of nodes and antinodes that are present (include the ends of the string in your count).c. Which of the five harmonics has the highest natural frequency?d. Make a drawing that shows what the sixth harmonic would look like.

more than, less

less than, more

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
