Under the action of what force is a spring with a stiffness of 1000 N / m compressed by 4 cm?

Given:
hardness k = 1000 N / m
is compressed by x = 4 cm = 4 * 1 cm = 4 * 0, 0 1 m = 0. 04 m
spring force unknown
find the force of the spring F -?
Solution:
F = k * x = 1000 N / m * 0. 04 m = 1000 N * 0 4 = 1000 * 0 4 N = 10 to the power of 3 * 4 * 1 0 to the power (- 2) H = 4 * (10 to the power 3 * 10 to the power (- 2 )) H = 4 * 10 in the power (3 – 2) H = 4 * 10 in the power 1 H = 4 * 10 H = 40 H
Answer: 40 N
