Question

A 25 N force stretches a spring 280 cm. What was the spring constant? ​

Answer 1

1. F= 25N
2. ∆l=280cm
3. K=?
4. you apply the formula = K:F/∆l
5. = 0,089N/cm

Answer 2

Hi there!

Using Hooke's Law:

F = kx

F = Force (N)

k = Spring constant (N/m)

x = displacement (m)

Begin by converting cm to m:

280 cm = 2.8 m

Now, plug in the givens:

25 = 2.8k

k = 8.93 N/m
