The highest frequency of a piano is about 4200 Hz. What is the wavelength of the sound wave in air, if the speed of a sound wave in air is 340 m/s?

it breaks and dirupture other materials and other sencews from the bottom

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
