A neutron star is . a star made mostly of elements with high atomic mass numbers, so that they have lots of neutrons the remains of a star that died in a massive star supernova (if no black hole was created) the remains of a star that died by expelling its outer layers in a planetary nebula an object that will ultimately become a black hole

conduction, convection, radiation

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
