Explanation:
Given that:
Height of jump,
length of elastic cord,
spring constant of the cord,
mass of the body that jumps,
Force on the bungee elastic cord:
Now this force F will be responsible for the elongation in the elastic cord, so:
............................(1)
where :
k = spring constant
x = extension in the elastic cord
using eq. (1)
So the cord stretches 19.6 meters more beyond its original length of 30 meters.
Hence, the remaining distance from the river surface at the bottom is:
