Yes. The height of the ramp does affect the speed going down it the higher the ramp the faster the car goes down it
how does increasing the height of a ramp affect how far a ball rolls down the ramp

Changing the slope of the ramp will affect the speed of the vehicle going down it.
Yes, bikes are safer than a skateboard because you can fall down when you do a flip over and you have to keep balance on a skateboard but you can hold on the handles and sit down on a bike.
Height directly affects gravitational potential energy, since this energy is equal to mgh (mass x gravity x height). Height does not affect kinetic energy, which depends on the speed, not on the height. Except indirectly - for example, if an object is falling down, its speed will usually increase.

It should not affect it too much because: # When you are lying down, the height difference is much less noticeable. # The human body is flexible and can assume many different positions where the height difference between partners does not matter.
