The rough surface is there to prevent people slipping over, especially if wet.
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.
It is alright for the surface of the ramp but not for the structure of the ramp.
yes because the smoother the surface is, the lower the friction ( the force that makes an object stop from a movement ) therefore, according to my science textbook; the rough textures have more friction and so, the texture of ramp does affect the speed of a toy car.
apply friction a rough surface cardboard for example, the rougher it is the slower the ball will roll but to much friction and it will stop altogether.
The smoother the surface of a ramp, the greater is the danger of a vehicle slipping and losing traction.A wet, smooth ramp could cause a pedestrian to slip over and be hurt.

a ramp is a flat surface which
A ramp can be considered a simple machine. It is a slanted surface that is often used to move things.
because it is a straight surface
An effort ramp is a slanted surface used to raise an object when direct lifting is not a viable option.
