The spectrum for visible wavelengths emitted by Star X is compared here to the emission spectra of four different elements. According to the spectral analysis data, which element is present in Star X?

if you answer my question i will answer yours

mass and volume are the answers you are looking for

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
