A delivery boy needs to know his projectile motion to throw a paper horizontally from a height of 1.40m to a door that is 13.5m away. What must the paper's velocity be for it to reach the door?

I tried using motion equations to solve this problem. I feel as if the problem isn't giving me enough information for it to be solved. Please help me if you can! Thank you!!

We know that bookies take bets from gamblers, but how do they "know" the correct odds for an event to happen? If they don't lay the correct odds, then they would lose. What are some of the math theories involved in determining the odds of winning / losing. Lastly, how is risk tolerance (or spread) determined by the bookie?

I know its ironical but what I have discovered is perhaps true...
Are there any jobs in India after a B.Sc. in Zoology with good grades? Please let me know the details if such jobs may be availible, now or in near future.

Also, are there any professional courses one can pursue after doing a B.Sc. in Zoology? One can carry on for a masters degree, but that doesn't seem good enough. I want some professional course that gives me some job, and don't tell me about having a B.Ed.!

Still, non-conventional job opportunities in India are really poor.
If you have some information that might be valuable, please answer my question.

Solar energy created by plants,"photosynthises" millions of years ago created fossil fuels we use today. Plants are still the most efficient users of the suns light energy to this today. Can we not as an intelligent species, or not, design or mimic this energy source?

What's your opinion.. ? Do zoos unfairly hold exotic animals captive for the sake of educational value? Or is it a cleverly masked and legalized version of trafficking them.
I am sure it is very stressful for the animals to be forcefully removed from their natural habitats.. and the same educational value could be found by watching National Geographic Explorer or similar programming..
But maybe others have different opinions.. ?
What's yours... ?

I am observing a rigid rod moving at half the speed of light, parallel to me. On the rod is a light source and a mirror. An observer is also on the rod. To the observer on the rod, light moves at the speed of light, both approaching the mirror and returning from the mirror. But to me as the "stationary" observer, light should also appear to be moving at a constant speed in both directions. Assuming the rod is approaching me at half the speed of light, how can it be that I observe light to be traveling at a constant velocity both toward the mirror and from the mirror while at the same time the observer on the rod sees this.

Grant me your wisdom oh theoretical physicist gurus...

If a lock has a 4-digit combonation needed to unlock and the numbers can be 0-to-9 (for example...1-2-3-4...is one possible combination to the lock).How many different possible combinations are there? and Is there anyway to get a list of all these combinations without having to handwrite them?

We have to be fair here. We as consumers do a lot of things that add to the degradation of our environment.

This could include exhausting or releasing or creating as a byproduct - pollutants, green house gasses, toxins, excessive heat, or any other harmful item or even using too much energy to perform the process, or wasting too much raw product or natural resource.

What do you think the worst thing is and how can we fix it?
