An 80-kg bungee jumper jumps off a bridge. Rubber bungee cords act as a large spring attaching the jumper to the bridge. A bear standing in the river below catches the jumper. If the spring constant of the bungees is 20 N/m and they stretch 50 m. How much force must the bear apply to keep the jumper from moving?

The force is

Explanation:

From the question we are told that

   The  mass of the bungee jumper is  m  = 80 kg

    The spring constant is  

    The extension of the rubber bungee cords is  x = 50 m

Generally the weight of the jumper is

=>  

=>   tex]W =  784  \  N  [/tex]

Generally  the returning force of the rubber bungee cords is mathematically represented as

=>    

=>    

The force to be applied by the bear is

=>    

=>  

i had this question and the answer was 3.15 miles.
