anyone here good at MATLAB Simulink?!!? I can't get this damn problem figured out and I'm willing to pay for help on how to do it.

I have two balls, one is a lead ball which is going at 60 mph while a follower ball is initially at 55 mph 20 ft behind the lead ball. I have to make this follower ball match the speed of the lead ball and maintain the 20ft distance exactly.

I have the equations of motion, but I literally can't do anything with them with so many unknowns. LET ME KNOW IF YOU CAN HELP AND WHAT YOUR COST IS because I really want to learn this
