Question How to limit bounciness on 2D physics material?

Hi I'm new to unity and for my first project I have created a single player version of pong using tutorials and my limited knowledge of C#. I wanted it to get increasingly harder so I set the bounciness of the physics material for the ball to 1.02 with 0 friction to make the ball boucne faster and faster. The problem is that eventually it becomes impossible due to the speed of the ball. So I was wondering if there was a way to set a limit on how fast the ball bounces. Thanks for your time!
