Who was the first astronaut to step outside of the Apollo 11 spacecraft, saying the now famous words “one small step for man, one giant step for mankind” as he placed the American flag on the rocky terrain?
Buzz Aldrin
Michael Collins
Neil Armstrong
Yuri Gagarin

Neil Armstrong

Explanation:

Neil Armstrong

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
