Abungee jumper with mass 58.5 kg jumps from a high bridge. after arriving at his lowest point, he oscillates up and down, reaching a low point seven more times in 45.0 s . he finally comes to rest 20.5 m below the level of the bridge. calculate the spring stiffness constant and the unstretched length of the bungee cord.

10.23077 m

55.88391 N/m

Explanation:

m = Mass of person = 58.5 kg

T = Time period =

k = Spring constant

g = Acceleration due to gravity = 9.81 m/s²

Time period is given by

The spring stiffness constant is 55.88391 N/m

The force on spring is given by

The unstreched length of the cord is 20.5-10.26923 = 10.23077 m

a, c, d, e are all applying about success strategies.

it would be kevlar ^^
