Abiological cycle, or rhythm, that is approximately 25 hours long is called

Circadian Rhythms

There are three types of biological rhythms.

→The one that occurs about every day (approx 24 hours) is known as Circadian Rhythms. For example, Hormone secretion, urine production, sleep etc.

→The one that occurs after more than a day like menstrual cycles of women (28 days) is known as Infradian Rhythms.

→The one that occurs more than once a day is known as Ultradian Rhythms like sleep, hormone levels etc.

Therefore, a biological cycle that is approximately 25 hours long is called Circadian Rhythms.

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
