Hooke's Constant - Bungee Jumping Example 1

See more videos at:

In this video, we look at how to find Hooke's constant in a bungee jumping example. Hooke's constant is also known as the spring constant or k-value.

Thank you so much whoever made this! I really appreciate it as i'm having extreme troubles in physics class!

my equation does not have the length of the bungee or the size of the person. It only has the mass of the person and the max stretch. How do I get the elastic potential energy?

Can you send the answer for this
Other end of an elastic cord attached to the ankles of a man with mass m is tied to a tall bridge. Man falls through a maximum distance H and get momentary rest then bounces back up. Maximum tension in the cord is four times the weight of the man. If the original length of the cord is L. force constant equals to,

it extended 28m not 8m right??? why is it 8m and not 28 for the extension

Thank you for the video! How is the gravitational potential energy decreasing? Isn't the person still at a height above ground?

[calseynez]

is this similar to differential equation falling bodies of Newton's 1st and 2nd law of motion. if not, then is it similar to the spring constant as well. i'm curious.

what was the point of finding the kinetic and gravitaional PE at the start, why not go to 80*10*30 straight away?

[danieljensen]

thanks! your teaching is really good. :D

[ninoengel]

Which two factors would you think define the "amount of bounciness"?

How can I find the rest of the videos?

9:03 you say he is slowing down, but he wont be slowing down before the tension in the rope is greater than his weight? He is still speeding up?

what is this whitebord program called?

I understand everything but one part. How is the change in kinetic energy 17600J, it went from 0 to -17600J so shouldn't it be -17600.

The jumper is gonna die. Practically speaking the bungee is too short and he would bounce back into the platform. A “workable” jump has way longer ropes so you ignore the hight of the jumper, just like you ignore the weight of the chord, air resistance etc 😜
