Homework Statement
A roller coasters weight increases 50% through the center of a dip in the track. The radius of the dip is 30m. What is the speed at the bottom?
Homework Equations
This is a uniform circular motion problem correct? But how do I calculate if I don't know the weight?
v = [tex]\omega[/tex]r
Fnet = mv2/r
The Attempt at a Solution
So is weight twice that of the normal force? Or the normal force has to balance it out by increasing by 50% as well?
Or should I be thinking in terms of [tex]\omega[/tex] instead of forces?
