I've been arguing with my physics teacher about why the deacceleration of a person on a skateboard or bicycle that is gliding along the ground (without pedaling or pushing) is dependent on the mass of the person riding it (The higher mass person goes further). I say that it is solely due to air-resistance having the same effect regardless of the mass (in this situation it is a person with 100lbs of lead in a backpack vs the same person without, so no greater area). He says that even in a vacuum, the heavier person riding the skateboard/bike would glide further.
