a roller coster car of mass 1500 kg starts at a distance of H=23m above the bottom of the loop 15 m in diameter. if friction is negligible, what is the downward force of the rails on the can when it is upside down at the top of the loop?
so what i was thinking is this:
f=ma and in this...
"The wheels of a certain roller coaster are both above and below the rails so that the car will not leave the rails. The mass supported by this particular wheel is 402 kg and the radius of this section of track is 70 m. What is the magnitude of the force that the track exerts on the wheel when...
49. You have been hired to design a spring launched roller coaster that will carry two passengers per car. Te car goes up a 10m high hill, then descends 15m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.0 m and that a loaded car will have a...
The height of the tracks of a roller coaster varies sinusoidally with the horizontal distance from its starting point. The roller coaster tracks start from the lowest point of the sinusoidal curve and reach a maximum height of 66 meters. The tracks return to the surface of the park for the first...
I have a quetion that I worked out and would love to know if I worked it out alright. Here it goes...
A roller coaster of mass 80kg is moving with a speed of 20.0 m/s at position A with a height of 200m. There is no friction and g=10m/s^2.
So basically there's a diagram of a...
Suppose the roller coaster in Fig. 6-41 (h1 = 38 m, h2 = 12 m, h3 = 20) passes point 1 with a speed of 1.40 m/s. If the average force of friction is equal to one third of its weight, with what speed will it reach point 2? The distance traveled is 35.0 m.

I always wondered what does it take to become a rollercoaster designer? What kind of schooling do you have to go through and of course...what kind of money do they make?
This is a bunch of bull. I'm watching an episode of Star Trek Voyager (my least favorite Star Trek) and my least favorite character (the doctor) made a family. His daughter dies in this episode and I'm crying. I swear I'm starting to get boobs. I don't know what's going on, must be my time of...
Riding a Loop-the-loop. A car in an amusement park ride rolls without friction around the track shown in the figure. It starts from rest at point A at a height h above the bottom of the loop. Treat the car as a particle.

As you may have noticed I've got a bit of a rollercoaster theme going.
My problem now is i have an 800 kg cart and I need to calculate the work done by bringing it to the top of the rollercoaster. The slope of the lift is 20 degrees and the maximum height is 30 m. From this i calculated the...
I am doing a project and one of the questions is to find the average force lost to friction. We measured a ball going down a "roller coaster" (it had 2 humps on it). WE have all the speeds and distances and accelerations, Now i calculated the energy lost to friction by taking the initial...
The owners of a fun-park are designing a new ride. This will have a section in the form of a helix whose central axis is directed horizontally. Patrons will travel along the helical path in carriages whose speed is a fixed value, u. The carriages will be upside down when they are at a high point...
