During which change of state do atoms lose energy? sublimation
freezing
boiling
melting

B) freezing

Explanation:

Because when something freezes, it turns to a solid from a liquid or gas. So, it loses energy. Solids have less energy because their atoms don’t have much space to move, making them vibrate in place.

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
