The soft cloth does not have an effect on a rigid physics object. Only the other way around. Soft cloth can effect other soft cloth, but that won't really help in your situation.
Maybe you can set up some strategic rigid props to slow the ball down. You would then make those dummies so they would be invisible. Maybe a brick wall would work? Give all the bricks a large amount of damping. Not sure if there is a way to keep said bricks from effecting the cloth of the net.
So basically, a bunch of kinetic energy absorbers.
EDIT:
Just thought of a way to do it with a bunch of cylinders (rigid) connected by constraints in a lattice configuration.
