Without a calculus explanation; you can say that the only forces that act on a bungee jumper is F(gravity), and F(rope), and friction.
F(gravity) is the force of gravity that pulls the jumper down
F(rope) is the force of the rope that is tension that will later keep the jumper from slamming into his death
and friction, due to the air.
The formula for free fall acceleration is delta y = (vinitial)(t) + (1/2)g(delta t)^2 (which only happens when, hopefully never happens, the bungee rope breaks and you are no longer attached, yikes!).
Aww, no "advanced" calculus? Maybe a little basic calculus, or rather algebra, or none at all. The F(rope) mentioned above is not actually a constant force, since it results from the elastic bungee attached to the jumper. The force is actually proportional to the distance it is stretched: F = -kx, negative being that the force is in the opposite direction of the displacement (i.e. you pull a spring left, the force pulls it back to the right). Since the force is not constant throughout the entire "trip" the force you experience is not constant, resulting in higher "g" force at the bottom of the fall, and instantaneous free fall at the top of the recoil.
Ok, maybe a little calculus to satisfy me and other people who may be interested in the Calculus. There is still time to hit the back button.
Alrighty, Since you are falling, there is a change in potential energy due to gravity: delta U. Since U = -W, and W = integral (F x dx ), W = integral (-kx dx) (from above equation), which integrates to (1/2)kx2, therefore U = -(1/2)kx2. Using this equation, you can find the period of oscillation for this dampen oscillation (since energy is lost to heat and gravity does work on the system). That wasn't so bad was it?
The three forces acting on the bungee jumper are gravity pulling the jumper downward, tension in the bungee cord pulling the jumper upward, and air resistance opposing the jumper's motion through the air.

Jumper error. 99% of the time the reason the jumper dies or is injured is because they, the jumper caused a equipment failure or a misscalcualtion if it is a self bungee jump.
Gravity, rope, and friction
To explain this, you will need to keep in mind a mathematical formula: Force applied on bungee jumper = mass of bungee jumper x (initial speed - final speed) / time taken for change in momentum F = m x (vi - vf) / t Let's say the bungee jumper was falling at an initial speed of vi. If he was to be halted, the final speed, vf = 0. If he was halted very suddenly, i.e. in a short time, the value of Force applied on the bungee jumper would be very large, which would be dangerous. Now if he was to be halted gradually over a longer period of time, the value of the force applied on him would be smaller, slowly decelerating him until rest.
Well, it depends on what you mean. If you mean when they bungee jump, then it helps them not fall and it stretches to a distance there it will pull the bungee jumper up or to a certain height.
One should thoroughly research the equipment, safety measures and physical requirements involved before becoming a bungee jumper. Taking classes is recommended to avoid possible tragic consequences of being untrained.
Bungee jumping equipment would cost about one hundred dollars, depending on how intense you want to bungee jump. If you are a casual jumper, then it should cost about one hundred us dollars.
Useful energy would be the potential energy stored in the bungee cord when it is stretched out at the top of the jump, which is converted to kinetic energy as the jumper falls. Energy that is wasted would include any sound, heat, and other forms of energy dissipated as the bungee cord stretches and returns to its original length.
The oldest bungee jumper that I have seen documented, is Mohr Keel, who jumped at age 96, from the Bloukrans Bridge in South Africa. I have seen a claim on a bungee site, saying that the oldest bungee jumper was age 100, but I can only vouch for the 96 year old.
