Rusty pickins, a gold miner, has just found a chunk of gold. rusty would like to change the gold from a solid to a liquid, so that he can pour it into bars.
which does he need to do?
a.) add heat to cause a chemical reaction to occur.
b.) add heat to increase the molecular motion of the atoms.
c.) add heat to change gold into a new element.

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
