Yes,
As a Boy scout we would weight our cars so that they would travel faster.

I cannot say about "lenght", but distance is a measure of length so length affects distance. Speed is the rate of change of distance (over time) so length affects speed. Mass does not significantly affect speed or distance but, because they are affected by acceleration and acceleration is affected by mass (for a given force), then mass affects them. Also, mass affects space time and the presence or absence of mass changes the lines along which distances are measured and so distances and speed are affected.

The car's mass should have no effect on that speed.
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.

Mass does not affect the acceleration of an object due to gravity. Any object of any size or mass will fall at the same speed. A ball rolling down an inclined plane is accelerated by gravity, so its speed won't be affected by its mass at all.
The mass and the trajectory of the object affect the speed at which the object will roll.

Yes the weight does affect the speed of a skateboard.....if your 90 pounds and your ridding with a 105 pound person the 90 pound person will go faster!!!!
The more mass it has, the faster it will fall and vice versa.

A greater mass creates a stronger gravitational pull.
