Question

What is the magnitude of the force required to stretch or compress a spring of spring constant 50.0 N/m a distance 2.50 cm from its unstrained length?

a. 50.0 N
b. 125 N
c. 20.0 N
d. 1.25 N

Answer 1

Magnitude of the force = 1.25 N

Step-by-step explanation:

Given:

Spring constant k = 50.0 N/m

Distance s = 2.50 cm = 0.025 m

Find:

Magnitude of the force

Computation:

Magnitude of the force = Ks

Magnitude of the force = 50 x 0.025

Magnitude of the force = 1.25 N
