heart failure, heart attack,

Explanation:

heart failure, heart attack,

coronary artery disease, high blood pressure, heart attack, heart failure are some examples

the answer is mosques. they are an important part of islamic culture.

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
