Homework Statement
I am trying to calculate the speed and force needed to make a marble complete a loop in the rollercoaster that i have been instructed to make. I do not know how to calculate f though. I can not use v=d/t becuase I can't find time until the rollercoaster is built which I cannot build until I find the force needed to get the marble to go through the loop. How do i find f?
Radius (arbitrary) = 11 cm
= 0.11 m
mass = approx 3.56g
Homework Equations
T = 1/f
v = 2πr/T
FR =mv^2 / r
The Attempt at a Solution
v = 2πr/T
= 2πr/(1/f)
= 2π0.11/(1/f)
=0.6911503838/(1/f)
FR = mv^2/r
= 3.56v^2 / 0.11
= 32.36363636v^2
= 32.36363636(0.6911503838/(1/f))
π is supposed to be pi, the alt code I found did not work sorry
