Block B is initially at rest on block A, which is at rest on a smooth frictionless floor. There is friction between block A and block B. The coefficient of static friction between the blocks is 0.300 and the coefficient of kinetic friction between the blocks is 0.250. mA = 5.00 kg and mB = 3.00 kg. A horizontal force of F = 14.0 N is applied to block A. What is the magnitude of the frictional force on block B?
-if you could show what steps you used to get the answer, that would be great :)

having been "rotating around the sun" for 16 billion years, (ejected from Mars' surface from an asteroid hit).

Then it "came into the gravitational pull of the earth" and ended up in Antarctica, (on the surface, I assume), 13,000 years ago, according to scientists.

Now all this rhetoric regarding "how it got here" is what I question.

The escape velocity (to have an object escape the gravitational pull of gravity) of the earth is about 17,000 miles per hour. It takes one helluva propulsion system to accomplish this.

Mars. being of much less mass/gravity requires about 40% less than that, say 8,000 mph escape velocity.

I cannot/willnot believe that an asteroid kicking up some rocks on Mars can result in those rocks being propelled into space at 8,000 mph (unless someone can prove to me with some viable figures to support such a theory).

There is nothing to prove that ALH84001 DID NOT come from the asteroid belt- between Mars & Jupiter.

Escape velocity needs answer.

If you can find a link to a good website that does this, that would be great as well.
I always best anwer my questions.

Is this true? I can't find any evidence to back it up. Is it just some crap people are spouting to make the similarity between human and chimpanzee genes seem irrelevant?
