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

In a spherical bowl a small ball is jumping around. The ball hits the bowl in two spots and moves in two different trajectories in times T_{1}, T_{2}. Find the radius of the bowl.

2. Relevant equations

Newton's laws of dynamics.

3. The attempt at a solution

The only thing I could figure out is how the horizontal velocities of different trajectories are related:

[tex] s=v_{x1}⋅T_1=v_{x2}⋅T_2 ⇒ \frac{v_{x1}}{v_{x2}} = \frac{T_2}{T_1} [/tex]

But I can't find a way to get any expression with the radius. Please help.
