Oh, I think there is a misunderstanding. The car doesn't travel all the way around the circle. The circle is just there to show the curve of the track after the straight part. After it reaches the lowest point it doesn't go up, it continues straight, but that's not part of the problem anyways...
I could calculate that the circle and the straight part of the track meet at a height of 1.9m
The function for the normal force is:
f(x) = gravitational force*cos(x)+centripetal force or in terms of numbers f(x) = 6200*cos(x)+16740
x is between 0°(at the lowest point of the circle) and 40°(where...
My high school teacher gave this problem so I thought it's introductory. I don't know the maths for that, but I think it has something to do with finding the area below a curve. I can look it up if that's what it takes to solve this. Could you give me some hints on how to go on from here?
Homework Statement
A roller coaster is going down on a track (see image below, the track itself is highlighted in red) without initial velocity. What is the coefficient of friction between the roller coaster and the track?
height at which the cart starts (h) = 12m
weight of the car (m) = 620kg...
Homework Statement
I'm making a program that draws a graph of the weight of an hourglass. Obviously at first we know the weight, and as the grains begin to fall it decreases by the amount of mass in free fall. However I ran into a problem when the grains begin to hit the bottom. It's impossible...
