Solve the problems and show the complete solution.
1. If an object is hanging from a spring that causes the spring of k = 80 N/m to stretch by .04m.
a) What is the Fnet of the spring? Fnet = k x
b) What is the mass of the object? m = F/g

Answer 1

a) $F_{net}=k|\Delta x|=80\cdot0.04=3.2(N)$

b) $mg=k|\Delta x|\to m=k|\Delta x|/g=80\cdot0.04/9.81=0.33(kg)$
