The recommended slope for straight ramps in situations such as:

17 inch
Changing the slope of the ramp will affect the speed of the vehicle going down it.
You can stop a toy car from going down a ramp by placing a barrier at the end of the ramp, such as a wall or a book. Another option is to alter the slope of the ramp to make it less steep so that the car doesn't pick up enough speed to continue rolling. Additionally, you can manually hold the car in place at the top of the ramp.
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.
The steeper the slope of a ramp, the greater the amount of force or energy required to move an object up the ramp. A steeper slope will require more work to overcome gravity and friction compared to a shallower slope.
yes
it is radius of smallest circle that can be drawn by the vehicle during turning.
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).
