Two objects leave from the same point at the same time in the same direction. One has a velocity of 350 m/s, the other with a velocity of 700 m/s.

The second object, at some point, is two seconds ahead of the first object. What is the total distance travelled by the second object at the point at which it is two seconds ahead of the first object?

Some help me, as I am having a brain fart. Here's the problem:

A certain marine sees a sniper 895 yards away (as per her lazer range finder). She drops down behind a berm to ask permission to kill the sniper, and then sees a bullet impact the top of the berm where she was a few seconds prior. Exactly 1.000 seconds later, she hears the report of the sniper's gun.

Given that in this location, the speed of sound is 1147 feet per second, what is the average velocity of the bullet that the sniper fired?

Thanks!

Doesn't the 2nd law of thermodynamics imply that a constant speed of light is impossible?

In the light of experimental evidence showing that the speed of light IS SLOWING DOWN, what would the ramifications of this be?¹

*Could it be possible that rainbows didn't exist before the biblical account of Noah's flood?

*Could it be that the universe is NOT expanding as fast as "red-shift" measurements indicate--indeed, is it possible that the universe is not expanding at all?

*quantized red-shift observations from other galaxies

*measured changes in atomic masses over time

*measured changes in Planck’s Constant over time

*differences between time as measured by the atomic clock, and time as measured by the orbits of the planets in our solar system

Pick a positive real number and take the square root of it. Add one to that answer. Take the square root of that answer. Again, add 1 to the answer you now have. Again, take the square root of the answer. Continue in this fasion until you have reached some limit.

Here's the question: what is this very famous number?

If you had a parabola, say, y = x², and you were to rotate it 45° so that it was symmetric about the line y = x, what would the equation of this rotated parabola be?

Then why are you trusting Mitt Romney?

A certain country borrowed some money. At the instant it owed $16,000,000,000.00, it was paying $45,000.00 per second in interest.

Assuming the interest is being compounded continuously, at what interest rate had this loan been made?

Falska, a member of the swedish bikini team, went to a waterpark & decided to take a ride down a giant water slide. Assuming that there was no friction between her and the slide, and knowing that the slide had a straight, non-curving descent, what is the angle of the slide relative to the ground if she fell 33 meters of slide-length in 3.3 seconds?

How fast was Falska travelling at the end of the 3.3 second ride?

What is the difference between "The United Kingdom," "Great Britain," and "England?"

No disrespect is meant by the question; I just don't know, and my parents were asking. Nobody in our family has lived "accross the pond," so to speak.

What say you all?

How many people, in the history of the world, have died, prior to today? Given that the population of the world today is 6.98×10⁹ people, when, if at all, has the current population of the world equalled the total deaths in world history. If this statistical curiosity has not yet happened, when will it?

I look up as I walk

So that the tears won't fall

Remembering those those spring days

But I am all alone tonight

I look up as I walk

Counting the stars with tearful eyes

Remembering those summer days

But I am all alone tonight

Happiness lies beyond the clouds

Happiness lies up above the sky

I look up as I walk

So that the tears won't fall

Though the tears well up as I walk

For tonight I'm all alone tonight

(whistling)

Remembering those autumn days

But I am all alone tonight

Sadness lies in the shadow of the stars

Sadness lurks in the shadow of the moon

I look up as I walk

So that the tears won't fall

Though the tears well up as I walk

For tonight I'm all alone

In a certain population of alien humanoids on the planet Sirius X, the probability of a female alien getting pregnant when she does not use the one and only form of birth control available to the species (barring abstinence), based on having sex at random whenever her mate wants to have sex, which occurs at totally random times (but not necessarily whenever she desires, which is not random), is 0.15.

The probability of her getting pregnant under the same conditions when birth control is used is 0.015, that is, her birth control is correctly advertised "to be 98.5% effective at preventing pregnancy when used as directed."

On a day when the probability of getting pregnant without birth control is near 1.0, what is the probability that, given that they have had sex, they will not become pregnant while using the birth control?

I have noticed some voltage ratings for 12VDC power sources/supplies that seem to frequently pop up. I keep seeing the following voltages:

12.2 VDC

13.8 VDC

14.4 VDC

What, if anything, is significant about these numbers?

I have a piece of wood "x" inches wide, and I want to saw it into exactly "n" equal-sized pieces, with no wood left over (other than the sawdust made by the cutting process). The width of my saw blade is 1/8". How wide will each equally sized piece of wood be?

If I were to cut 10, 3-inch boards from a piece of wood, using the same 1/8" saw blade, what total width of wood would have had to have been cut?

A particular coin has two sides to it, as do many coins: a heads side, and a tails side. For whatever reason, the probability of flipping heads is 0.49999. The probability of flipping tails is 0.49999 also. The probability of the coin being flipped neither heads nor tails is 0.00002.

What is the probability of flipping heads twice in a row?

What is the probability of not flipping tails, two times in a row?

I have 100 capsules in a box. 99 are empty, 1 has a prize in it. I pick a capsule at random, and see if it has the prize. If it does, I stop. If it doesn't, I remove it from the box, and keep choosing capsules in the same fashion until I find the prize.

After picking how many capsules can I reasonable expect to find the prize, statistically speaking?

At what angle should the curves be banked, and, at what radius must the curves be so that lateral g-forces do not exceed 2 g's, and g's in the downward direction do not exceed 5 g's for more than 5 seconds, assuming that the cars traverse the curves at 94 meters per second?

A rocket has a constant thrust of 120 kg. At time t=0 sec, it has a mass of 100 kg. At time t=5 sec, it has a mass of 10 kg. What is its velocity after 5 seconds? How high will the rocket go? When will it hit the ground?

f(x) = x⁻ᵉ + eˣ

g(x) = x^(e/pi)

These two functions do not have any points in common. What is the minimum distance between the graphs of these two wild and crazy functions?!?

A particular bowler wants a "balance hole" drilled into her ball. A drill bit with a diameter of 1¼ inches is used to drill a single hole into the bowling ball, which happens to have a circumference of 27 inches.

How much of the ball's surface area is removed after drilling?
