Either decrease the slope of the ramp, increase the friction on the axels of the car, or make the tires stick to the ramp in some fashion.
Yes. The height of the ramp does affect the speed going down it the higher the ramp the faster the car goes down it
Yes
Use a stopwatch.
You would need to measure the car's velocity at the top and at the bottom, and the time it took to go down the ramp. Acceleration = change of velocity/time.
The weight of the car will cause the force of gravity to push it down with seemingly more force than the lighter car. And so this would make the car go faster down a slanted surface, which is the ramp.

Changing the slope of the ramp will affect the speed of the vehicle going down it.
The larger the angle of the ramp, the faster the car will go down it.

Yes because the toy car will be forced to speed up the steeper the ramp it's like going down a hill on your bike you speed up because of OME'S law.
That depends on the toy car's weight, size, and the length and height of the ramp. Use science and math to figure this out.

Gravity and friction !
In optimal conditions such as infinite runway, performed in a vacuum, with a constant gravitational pull and a zero friction ramp the car could travel at the speed of light. For anything else it would depend on the ramp and the car. Also at what point you stop calling a ramp a ramp and start calling it a drop.
One factor is the height of the ramp. The higher the height of the ramp the further the car travels. Another factor is the surface of the ramp. With a rough surface on the ramp e.g sand paper the car travels a short distance. With a lubricated surface on the ramp e.g Vaseline the car will travel a very long distance.
