A person can jump out of an airplane at 5000 feet, without a parachute, AND land on the ground safely (without any injury), IF they can manage to do what physics trick?

Lengthen the moment/time of impact
Bend knees right before impact
Spread out arms and legs to slow down
Shorten the length/time of impact

Answers

Answer 1

Answer:

Momentum is equal to mass for velocity (p1=mv)

But momentum is also equal to Force for time of impact (p1=Ft). Hence the impact force is inversely proportional to the fall time and directly proportional to the mass and fall velocity : F=mv/t^2 or F=p1/t

If he slows down, v diminishes and F diminishes

Hence correct Answer is C

Answer:

It demonstrates that the narrator is surrounded by nature.

Explanation:

Walt Whitman's "Crossing the Brooklyn Ferry" is a free verse poem written about the speaker's return trip on a ferry. He talks about his daily commute on the Brooklyn ferry, like the other commuters, and how they all share the same experience.

The given lines are from the very first stanza of the poem. The speaker repeats "face-to-face" when talking about nature. He sees the "flood-tide below" and the "clouds" high in the sky. This repetition demonstrates that he is surrounded by nature, amidst the throng of people around him. This shows the speaker's attitude of seeing the beauty of nature in any way he can, despite the bustle of commuting from Brooklyn to Manhattan.

Thus, the correct answer is the second option.
