I heard you can be fine for taking dirt or other particles , dead plants ,soil samples and to bring it back home.

Like I travel to Grand Canyon and want to bring back Spain for example. As to show that I was there ??

A 55 kg pole-vaulter falls from rest from a height of 5.0 m onto a foam-rubber pad. The pole-vaulter comes to rest 0.30 s after landing on the pad.
a) Calculate that athlete's velocity just before reaching the pad.

b) Calculate the constant force exerted on the pole-vaulter due to the collision.

Why do we not have "half-monkeys" walking around? Why has everyone COMPLETELY evolved if they are not a monkey, yet there are still monkeys?

I am not religious and believe more in science, but I just wonder these things.

So the universe is everything, right? I mean, that's the definition of universal, it's all-encompassing. So when scientists report that the universe is expanding, I get really confused. In what is the universe, an all-encompassing body, expanding? Seriously, think about it, if it (the universe) is everything, what holds it, how is it growing into something else????????

Well, we have found numerous planets around numerous stars beyond our own and now Voyager I has less that a decade before it passes into interstellar space.

Now, new ways must be developed to travel as quickly as possible so we might get to other stars to investigate these planets.

I have seen a few things on National Geographic but I was wondering if anyone who just scuffles about the internet has any personal (logical) ideas for space travel, manned and unmanned.

T(x,y) = (x^2, y)
Using the fact that T(u + v) = T(u) + T(v) must hold for it to be a linear operator, I reasoned that this transformation is not a linear operator. However, I would like confirmation on this simply because my prof is horrible and I do not know if I applied the property correctly.

A large mass (500kg) moving 10 m/s to the right collides with a smaller mass (5kg) which is initially at rest. The time of contact during the collision is 5 milliseconds. The large mass continues to travel to the right after the collision but at a reduced speed of 8 m/s.

Questions:

1. What is the magnitude of the force which these objects exert on each other?

2. What is the final velocity of the small mass?

Now reverse the situation. The small mass is moving to the right at 10 m/s and collides into the large mass which is at rest. The speed of the large mass after the collision is 1 m/s to the right (Assume that the time of the contact is the same as the previous example)

Questions:

3. What is the magnitude of the force which these objects exerts on each other?

4. What is the final velocity of the small mass?


Please show me how to solve this problem!

I understand that as we look at stars that we are seeing what happened in the passed due to the time that it took light to reach us. My confusion arises from the fact that at the time of the big bang, all mass was concentrated in a single point. Thus the mass of the star that we are observing and the mass of earth were at the time of the big bang at the same location and then separated at the big bang at a speed less than that of the speed of light. Thus if we look back at an object that is a billion light years away from us, then it must have taken more than a billion years for the particles that originated from the big bang to be separated by a billion light years. (This assumes that the particles raced away from each other at the speed of light). Thus when we see back in time we can never see before the time that it took for the particles to become separated by billion light years. Help!
