    How Much Higher Must the Initial Hill Be Than the Loop?

    Well I want to write h1 as a function of h2, so I don't see any other way to say it. I guess I must not be trying hard enough.

    How Much Higher Must the Initial Hill Be Than the Loop?

    Well here's what I'm doing, and I'm always getting h1 = h2/4. It's what I had done when I said one of my results for h1 was 1/2 Fc = FT - Fg = mV2/r FT = m(V2/r + g) Since FT - Fg has to yield 1g, or 9.8, I know FT = 19.6 19.6 = m(V2/r + 9.8) I'm operating under the assumption that...

    How Much Higher Must the Initial Hill Be Than the Loop?

    Honestly, I'm ashamed of myself. I know this is an easy question. Mass is canceled (at least when applyign the LCE), that much is obvious. The problem for me is that my h1 always ends up being a fraction of h2. I can't wrap my head around this and it's really getting on my nerves. I've...

    How Much Higher Must the Initial Hill Be Than the Loop?

    Homework Statement A roller coaster begins with a steep downhill descent followed by a vertical loop. How much higher does the initial hill have to be to than the height of the loop so that the riders experience a force of 1G keeping them in their seats at the top of the loop? Assume that...
