What is the ratio of intensities of two sounds of identical frequency if the first is just barely discernible as louder to a person than the second? ( 1db difference can be considered barely discernible.)

would be false hope this out

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
