Question: I just have a maybe slightly popular question.

You know the ski jumping sports. A friend of mine asked me if the distance of the jumper and the body weight could be related, neglecting the air resistance and physiological differences.

Thank you in advance for your help.

Answer: 
I will try explain it simply. 

In propagation on Earth we consider two things 

1. Kinematics
2. Kinetics

Kinematics only deals with velocity, acceleration, distance and not on any factors. 
Whereas Kinetics deals with mass, K.E, Force, P.E, etc

Now, if we apply same forces on two body simultaneously then at first we have to deal with kinetic equation to get the initial velocity 
Simply, 

F\*s = ½mu²............. Equation 1

You will get initial velocity u from the equation. 

And to calculate final velocity we now have to consider Newtons Kinematics equation 

v²=u²+2as................ Equation 2

Buy from equation 1 we understand that **initial velocity** will be smaller if the mass is heavy.

So the **final velocity** would be smaller from equation 2.

Conclusion :-For the same FORCE on two different body there would be two different velocity.
If you're neglecting external force both would be accelerated along the slide w/ $gsin \theta$ They would have the same speed at the bottom, and hence their range will be equal.
