Question

Solve the problems below and show the complete solution.

A vertical spring has a force constant k of 130N/m and a mass of 0.645kg is placed on top of it.
a) Calculate the mass of the object in N. F = w g
b) Calculate the x if the spring be compressed. F = k x
x = F / k

Answer 1

a)

$$F=mg=(0.645)(9.8)=6.32\ N$$

b)

$$x=\frac{F}{k}=\frac{6.32}{130}=0.0486\ m$$
