Answer:

0.064 m

Step-by-step explanation:

When a spring is stretched/compressed, the force exerted in the spring is related to the elongation of the spring by the equation:


F=kx

where:

F is the force applied

k is the spring constant

x is the stretching/compression of the spring

In this problem, we have:


F=8.22 N is the force applied by the kid on the spring

k = 128 N/m is the spring constant

Solving for x, we find how far the spring stretches:


x=(F)/(k)=(8.22)/(128)=0.064 m
