Hi guys, I have 11 roller coaster questions for my physics class, i tried doing them myself, but i haven't succeeded they are really hard, it takes like a genus to do them :( So I'd really appreciate any help with any or all the 11 questions.
-----------------------------------------------------------------------------------------------------
ok so the data:
-Track length= 1417m
-Train mass= 4536 Kg
-Greatest height= 38.7 m (first incline)
-Length of 1st drop= 44.8 m
-length of first lift= 100 m (Chain speed: 2.7 m/s)
-Maximum speed= 106.7 km/h
-Length of ride= 2 min, 23s
- Gravity forces= up to 1.65g's in the dips (1g=9.8m/(s)^2
----------------------------------------------------------------------------------------------------------------
Questions:
1- How long does it take for the coaster to climb the first hill?
2-What is the climbing angle of the first incline?
3- What is the maximum gravitational potential energy for the coaster as measured above the lowest point in the ride?
4- What is the average speed of the entire ride?
5- What is the maximum kinetic energy for the coaster?
6- Assume a speed at the top pf the 1st hill of 2.7 m/s and a vertical drop of 44.8 m. What should be the speed at the bottom of the hill with no friction or air resistance losses?
7- How large are the actual friction or air resistance losses in km/h?
8- How long is the track down the first drop?
9- What is the friction and air resistance loss per meter during the drop?
10- If the coaster had the same frictional and air resistance losses for the whole trip, would it reach the station?
11- Do you expect friction/air resistance losses to be greater or less in the latter part of the ride? Explain

Once again thank u so much for any input :)

What is physics the study of kids definition?
The dictionary definition of physics is "the study of matter, energy, and the interaction between them", but what that really means is that physics is about asking fundamental questions and trying to answer them by observing and experimenting.Physicists ask really big questions like:· How did the universe begin?· How will the universe change in the future?· How does the Sun keep on shining?· What are the basic building blocks of matter?If you think these questions are fascinating, then you'll like physics.
When was the magazine Physics Today first published?
Physics Today magazine was first first published in 1948. It is a scientific journal geared to people who are really interested in learning more about physics.
Important 10 mark questions in physics?
What is the relationship between mass and weight? Explain the concept of work and its relation to energy. Describe the difference between static and kinetic friction. How does a concave lens differ from a convex lens in terms of focal length? Discuss the properties and behavior of waves.
What is the meaning of p in physics?
nothing really it is just how they spell it
Is physics writing?
i really hope someone can improve this question but, all i know is physic is math and science together. i cant really think of an example. the last person that updated this is wrong physics is the study of living things
What do Yolanda and her sisters desperately want?
I wish people would answer these questions really every question on the internet should have a honest reliable answer, if not the website has no purpose ?

What do some people call an amusements park roller coaster?
A really big roller coaster.
Why cant i submit longer questions cause i have a physics question i need answered really bad?
Try to comment on your question! I'm not sure if you can.... try it!:)
Did they really make a roller coaster in the Barclay's advert 'roller coaster'?
Of course they didn't, its clearly done with computer special effects.
Is stress like a roller coaster?
it can be if you are really depressed and stuff like that!
Are you weightless when dropping on a roller coaster?
Not really, but on other parts you experience weightlessness
Where was the roller coaster first made?
Well that really depends the earliest ride that would be close enough to a roller coaster would be an equivalent of a luge run.
Is it true that if you are good at math you can do physics?
It really depends. If you are good at understanding the concepts of math and you think you can grasp the concepts of physics (which is not bad at all), then you will do fine in physics. Physics is like 50% math 50% concepts. This is my second year of physics (I am doing Physics with Calculus now) and it really isn't as bad as most people think.
Where can you rent a roller coaster?
well you cant really rent a roller coaster. in fact you cant even rent a roller coaster because you have to have more money than the richest people on earth. which i have no idea who the richest people on earth is anyway.
What is the relation of physics to psychology?
Not much, really.
