    Circular motion of a rollercoaster car on a loop-the-loop

    I'm so confused, isn't that why I used the rollercoaster's top speed for my calculation? So, is my starting equation Fy=N+Fg=mac incorrect?

    Circular motion of a rollercoaster car on a loop-the-loop

    Thank you for the quick respond and sorry for not being specific. Here's what I did: I considered the total force of the rollercoaster at the top of the loop: Fy = N + Fg = mac Then, I re-write the equation as: N + mg =...

    Circular motion of a rollercoaster car on a loop-the-loop

    Can someone please check if I got the correct answer. Thank you! I got: Fy= N + Fg = mac N + mg = mv^2/r g = v^2/r r = v^2/g r = (48.61)^2/9.8 r =...
