If the spring constant for a bungee cord is 0.056, then how much force will be needed to stretch the bungee cord 10 meters?

0.56 N
1.12 N
2.05 N
3.58 N
4.13 N

Explanation

Answer: A - Only 0.56 N of force will be needed to stretch the bungee cord 10 meters. Hooke’s law is F = kx, where k is the spring constant and x is the distance of displacement. Thus, F = 0.056*10 in this case, or 0.56 N.
