The farthest distance a mousetrap car has gone is approximately 1,650 feet, achieved by a team of students from the University of Nevada, Reno in 2016. Mousetrap cars are powered by the potential energy stored in a wound-up mousetrap, which is converted into kinetic energy to propel the vehicle forward. Factors such as the design of the car, the efficiency of the wheels, and the surface it is traveling on all play a role in determining how far the car can travel.

Velocity affects a mousetrap car by determining how fast the car can travel. A higher velocity means the car can cover more distance in a shorter amount of time. Factors like tire size, weight distribution, and surface friction can influence the velocity of a mousetrap car.
I would suggest building a motor first.
Because the axle is moving just as many rotations but since the wheels are bigger it's moving a greater distance. Because it's a big wheel, after all the string is gone, the wheels keep moving, which lets your car coast a longer distance.
you want to place your mousetrap as far away from the back wheels as possible
if you mean "how do you make a mousetrap pull a car's weight" then you do it through pulleys. for example, if a mousetrap exerted 10N of force and a car needed 10000N to pull it, the pulley you use would need a distance input : distance output ratio of 1000:1 (aka if you pull one side 1000 meters, the other side moves 1 meter). this would enable you to move the car theoretically, but in reality, the distance the car moves would be so small that it would be useless, and even then, it is more likely for whatever rope/chain you are using to just stretch slightly.
the smaller the wheel the lesser the weight, the mousetrap car would go faster,
A pulley system for a mousetrap car typically consists of one or more pulleys attached to the chassis of the car. The pulleys are connected by a string or rubber band, with one end attached to the mousetrap's lever arm and the other end attached to the axle of the wheels. When the mousetrap is triggered, the pulley system transfers the mechanical energy from the mousetrap to the wheels, propelling the car forward. The number and size of the pulleys used can affect the mechanical advantage and speed of the car.

because the wheel make the mousetrap go forward but without the wheels the mousetrap stays in one place
You can attach the mousetrap to the chassis of the mousetrap car, ensuring it is securely fastened in place. Make sure the mousetrap's spring mechanism is aligned with the drive axle to maximize the car's propulsion.
