Does mass always stay the same?
The mass of an object can be subtracted or added. For example, with water, you can just add more to have a larger mass. With ice, you can just chop off a portion to lessen its mass. Though, if you take a piece of paper and crumple it up, the mass will stay the same. It just depends on the context of the situation.
What happened to the shape of paper if you crumpled it?
When you crumple paper, its smooth, flat surface is distorted, resulting in creases and folds that change its shape. The paper becomes wrinkled and irregular, losing its original flatness and structure. This alteration is due to the physical manipulation of the fibers within the paper, which become compressed and rearranged. Consequently, the crumpled paper cannot easily return to its original form without flattening it again.
How far would it take to stop a 3900 pound car going 80 mph?
That all depends how good the brakes were, how good the tyres were and the road conditions (amongst other considerations, for example if the wheels lock and a skid ensues or not - the best braking occurs when the wheels are just about to lock up). If the brakes had failed, it would depend upon all the the friction available (in the wheel bearings, between the tyres and the road, air drag, etc). If the crumple zones were being tested, the car would be fired towards a rather solid lump of concrete, so with a suitable lump of concrete, the car could be stopped in no distance; however the car can be guaranteed to be rather shorter than before it stopped, but it still will not have gone any further than the concrete lump. Finally, if the emergency stopping distances as described in the highway code were used, the stopping distance would be 80ft thinking distance + 802/20 ft stopping distance = 400ft ~= 122m. Perhaps you can give some more information, specifically the braking force that will be applied?
Is a piece of paper 2 dimensional or 3 dimensional?
Well, isn't that just a happy little question? A piece of paper is typically considered 2-dimensional because it has length and width, but no significant depth. However, if you were to fold or crumple the paper, it could create a 3-dimensional form with height, width, and depth. Just like painting, sometimes it's all about perspective and how you choose to look at things.
How do you find the force with which something hits the ground if you know the distance and weight?
You can start by finding the change in energy of the object, which should be the work done on the object in the gravitational field: Int_(d0)^(d1) [F_g(r)] dr. If you're close enough to the surface of the Earth for the force of gravity to be the constant m*g, also known as the weight of the object, you can then get the simple equation (change in Energy) = dE = Wd where W is the weight of the object and d is the distance the object fell. This is also assuming negligible friction due to air. This is the amount of energy the object has to dispense when it hits the ground. (g is the acceleration due to gravity at sea level = 9.8m/s^2) The force with which it hits the ground depends on elastic properties of the object, ie., how much of the energy is wasted in deformation, frictional heat, etc. Whatever energy is not wasted in these endeavours is associated with the inelastic force between the ground and the object. A more useful thing to observe is the change in momentum of the object. Assuming the object is very inelastic and dispenses a minimum of its energy due to deformation or heat, we have the kinetic energy (1/2)mv^2 = Wd = mgd, so v = Sqrt(2gd) is the velocity with which it impacts the ground, while m*Sqrt(2gd) is the momentum it carries before it hits the ground. Force is change in momentum over time, so we have F = (W/(Tg))Sqrt(2gd) where T is the time it takes the object to decelerate to 0. This is why cushioning and crumple zones are important in decreasing the force imparted to people in car accidents, etc.

How do crumple zones prevent damage or injury?
Crumple Zones prevent damage or injury by supplying a place in the structure of the frame to crumple in an accident.
What are the advantages of the crumple zone?
A crumple zone absorbs energy during impact.
