After reviewing previous works and studying on the information from physic books, and measurements of the ramp, to design some of solutions to solve the problem. It had to be put to consideration of the rules to the challenge and the best possible advantages to having certain parts on the car. Referring back to other previous works and the AP physics book helped me understand better which design could have better velocity, coefficient friction, momentum, and elastic collision, Here are a few proposal that have been calculated and thought over:
