In Samples/physics/cloth_02, first red ball penetrate through Cloth (sometimes 1 out of ten).

I assume it's your physics calculations that are not too accurate.

 

You can change the setting in the editor or by script, look for "Physics Settings" and "FPS" in the editor

Cloth is simulated as a grid of spheres (called particles), that's why when you throw a ball into it, it pulls particles apart and moves further. What you need to do is:

1. Increase the radius of particles.
   
2. Increase the mass of particles (they should be very heavy, so that the ball bounces off them rather than moves them).
