I have two math problems that I can't figure out.
1. What is the instantaneous velocity of a freely falling object 10 s after it is released from rest? What is the average velocity during this 10-s interval? How far will it fall during this time?

2. Kenny drops his physics book of a balcony. It hits the ground below 1.5 s later. With what speed does it hit? How high is the balcony? Ignore air drag.

Any help would be appreciated.

I tryed to foil Evaluate/Simplify: ( x - 1) (2x + 3) but I seem to end up with 2x^2+3x-x-2 but the answer is 2x^2 + x - 3. Where did I go wrong?

A crt works with electrons hitting a phosphor screen not with light.
light being a paticle..nonsense..if u cut a million slits in a piece of card and shine a light its the same wave going through these slits but divided into a million pieces but still carrying same information.
light being self propagating is like saying perpetual motion exists.. it need energy to sustain it.
light is not affected by gravity however the fabric of the universe is.
stretch the fabric into long thin lines also affects the light

We are a family of four and 2 dogs from a European country.
We're intending to build a deer farm with cultural and traditional touring and hosting activities.
We need a partner, or even more, depending of situation. We’re searching for someone with a real love for nature and its treasures, for animals and country life, culture and traditions, which is ready to invest not only money but soul, love, hope and patient. Skills or experience in deer farming are not necessary, we could learn together.
For anyone who’s interested we have more details, explications, materials, photos, and any information are needed.

how did antimatter figure into Star Trek? Would it really work? If you aren't a Trekkie you may have to find an old episode - they're on all the time!

has anyone ever thought of how assanine it is for the government to spend billions and billions of dollars on the space program, trying to find out if there is other life, when they should just be worried about the life on this planet, and make sure that they are all fed and clothed and housed properly???

i mean,learning about mars and jupiter,and landing on the moon is all very exciting and enlightening,but,can we get real????
did we really need to know that pluto was never really a planet?? did that really help anyone??? i just don't get it!!!!

As a ship gets farther from earth, it's radio transmission beome more gapped - so if a spaceship were to continuously transmit, what would happen to signal we receive? Would it be constant as well because the signal would catch up with itself or would it become slower?
