i’ve taken airplanes while traveling but i never understood how airplanes get from point A to B in the sky?

There are several methods to get to where you want to go in an airplane.

The first and most basic is navigation by land marks, lakes, roads, other airports, mountains…. the list goes on.

Next comes radio navigation, there are things called VOR’s all over the country and with the proper equipment you can fly to or from a near by one and a lot of them are at or near airports.

Next if you plane is equiped with GPS it is a no brainier, just punch in the airport code and it will guide you right to it.

Lastly all big planes and some small plane that are flying IFR under control of Air Traffic control. ATC tells you what direction, speed and altitude to fly to get to your destination.

Am relocating and will need to set up a bank account upon arrival. I need the funds available immediately, so I figured (correct me if I’m wrong) carrying cash to open the account would be the best way to go. Since I don’t know much about traveling on airplanes, maybe you all could advise me on whether to hide the cash in my luggage, elsewhere or carry it taped to my body ( :

Go to a travel store and invest in a money belt or a security pouch. Keep it tied to your waist all times. If they make you take it off at the x-ray machine, make sure you keep your eye on it and grab it as soon as it comes out of the machine.
Do not check it in with your luggage.

Instead of carrying cash, I would go to a local bank and exchange the cash for a cashier’s check. These are recognized as guaranteed funds by all banks (as good as cash but safer). However, amounts above $5000 are subject to deposit holds and some of the more paranoid banks may not issue you cash from a cashier’s check until it clears.
Contact the bank at your destination and find out what their policy is.

1) An airplane flying at 115 m/s due east makes a gradual turn following a circular path to fly south. The turn takes 15 seconds to complete. What is the magnitude of the centripetal acceleration during the turn?
a. 12 m/s2
b. 9.8 m/s2
c. 0 m/s2
d. 6.9 m/s
e. 8.1 m/s2

2) Two cars are traveling at the same constant speed v. Car A is moving along a straight section of the road, while B is rounding a circular turn. Which statement is true about the acceleration of the cars?
a. The acceleration of both cars is zero, since they are traveling at a constant speed.
b. Car A is accelerating, but car B is not accelerating.
C. Car A is not accelerating, but car B is accelerating,
d. Both cars are accelerating.

3) What is the mass on Mercury of an object that weighs 784 N on the earth’s surface?
a. 80.0 kg
b. 48.0 kg
C.118 kg
d. 26.0 kg
e. Not enough information given.

1) ma = mv^2/r

a= v^2/r
a = 115^2 / r

find ‘r’ by figuring out how much it travelled (this will be a quarter of a circle since it makes a 90 degree turn).

d = 115 x 15
d = 1725m

C = 1725 x 4 (since its a quarter)
C = 6900m

now find ‘r’

C = 2pi*r
6900 = 2pi*r
r = 6900/2pi
r = 1098m

plug info back to a=v^2/r

a = 115^2 /1098
a = 12.04 m/s^2

2) C…constant speed on straight road = no accel and since B is in circular motion…direction always changes..therefore accel on car B.

3) you need to find the Fg on Mercury…then use F = mg

I’m guessing a helicopter is useful for traveling short distances in safety + transporting cargo. Control.

How far can jet airplanes travel and is it far more dangerous than a chopper? and where would you use a jet airplane if you had hundreds of millions of dollars?

Helicopters are actually LESS safe than jets, although both are still relatively safe. The only advantage of a helicopter is flexibility: Whereas a jet can only operate from airports with long enough runways, a helicopter can land in any clearing large enough to fit the helicopter in (You usually want more space than that, but talk to a helicopter pilot who served in Vietnam. They had some pretty dicey experiences.).

However, jets are safer, cheaper, faster, more reliable, can carry thousands of tons of cargo, and can fly halfway around the world in less than a day, nonstop.

Why do you ask?

Im not sure if i understood the question but i think you mean to ask how to ID an airplane. And this is not somthing that you will learn over night. This takes years of doing. I started when i was around 7 and i am 18 i know what every plane looks like and sometimes i dont need to see them i can hear what they sound like and ID them that way. The way i ID aircraft is first how many engines they have where the engines are, size, wing loacation, horizontal stabilizer location, once you can catigorize aircraft in a general group you can move on to the next step. That step is looking at the features they are just things that make an airplane different from others. Such as all 737s have a small horizontal shape to the tail before it starts. The md-11 has winglest that no other plane has because of its shape. Things like that and with a lot of practice you will master this art. its a lot of fun and impresses everyone how i can just look at a plane in the sky and know what it is.
