'i don't know is that was disturbing or useful or confusing' heehee

I am very happy to see the vidoe How fast does a car need to go to complete a loop-d-loop after you give this
-
I Love The Video It Can Increase My Knowledge How fast does a car need to go to complete a loop-d-loop.
-
Steady I Really Like This Video How fast does a car need to go to complete a loop-d-loop
-
Watching your videos makes me want to be home-schooled.
-
Sal, your videos are comforting.

@bubbleteddies Because Fn and Fg act as Fc (the force towards the center) so I considered both of them when doing the formula Fnet=mac

7.71m/s (for the answer below)

Please correct me if I'm wrong but I dont think this is correct. Since you're trying to find the minimum speed it must go to offset the loop, shouldn't you consider Fn as a force as well. Fg and Fn are both going downwards so according to newtons second law the equation would be Fg+Fn=ma. Fn must be 0 as that is the minimum to complete the loop, making the equation Fg=ma. Fg=mg and a=v^2/r so the new equation would be mg=m(v^2/r). Masses cancel out so the new equation is g=(v^2/r) making v=7.71

i never get tired listening to you
thank you

great videos! Sure, but why from one moment to another he start using feet's as the magnitude ? in my country we use meters and I am not costume to feet's. Even do, that's not a big deal.
