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

Derive an expression for V_{min}, the minimum speed the ball can have at point Z without leaving the circular path.

2. Relevant equations

V≤(x/t)

V≤(2∏r)/(t)

V=√(GM_{1})/(r)

3. The attempt at a solution

I set 2∏r = to x since its in a circle. i then had V≤(2∏r)/(t)

then i had (2∏r)/(t)=√(GM_{1})/(r)

in the end i got t=2∏√(r^{3})/(Gm_{1})

it didnt make sense to me so i came here for help /:
