A 919 kg rollercoaster is about to go up a hill that acts as the top of a circle 16.21m in diameter. What is the fastest that car can move (in m/s) without leaving a track?

known:

mass: 919 kg

diameter: 16.21

radius: 8.105

2. Relevant equations

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

[tex]\omega[/tex]=[tex]\theta[/tex]/time

3. The attempt at a solution

i have no idea how to work this out with out knowing the time or speed or somekind of time measurement. Is there another way to solve this?
