physics study

I'm looking for someone to help me with a physics study. I'm looking to find the maximum speeds of a pickleball that will go in from different heights from the end of the court and the ability to negate a pickleball speed from the net.

You must know the dimensions of a pickleball court and the angles you can hit it from.
