The recommended slope for straight ramps in situations such as:

Regulations for other countries may vary.
17 inch
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.
Changing the slope of the ramp will affect the speed of the vehicle going down it.
it depends...a ramp with transitions at top and bottom can be steeper than one without, because severe change in slope can cause the vehicle to bottom out.
17' radius
The maximun slope of an ADA ramp is 8.3% or 12:1.
check this site. you can find usefull information.
yes
it is radius of smallest circle that can be drawn by the vehicle during turning.
Air resistance against the car as it travels and the friction of the wheels against the ground slows it down and so reduces the toy car's potential travelling distance The weight of the car\on the car, the slope of the ramp and the material the car lands on or on the ramp
The answer depends on what causes the difficulty: the steepness or the distance which you have to run.
- The slope and length of the ramp. - The rolling friction between the tires and the ramp/ground. - The air resistance (which is dependent on the velocity and geometrical shape of the car). - The direction and speed of the wind. - The smoothness of the ground (a rugged surface will slow the car down).
