(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

This is a uniform circular motion problem correct? But how do I calculate if I dont know the weight?

v = [tex]\omega[/tex]r

Fnet = mv^{2}/r

3. 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?
