Imagine you drew back a bow and fired an arrow at a target such as a mound of hay with a bulls-eye on it. Describe the potential and kinetic energy conversions taking place from the time you begin to pull back on the bow string to the time the arrow hits the target. (Hint: there are 3 stages here.)

conduction, convection, radiation

your answer is, orbit around the nucleus

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
