Homework Statement
A ball of mass 560 g hangs from a spring whose stiffness is 185 Newtons per meter. A string is attached to the ball and you are pulling the string to the right, so that the ball hangs motionless. In this situation the spring is stretched, and its length is 15 cm.
What would be the relaxed length of the spring, if it were detached from the ball and laid on a table?
Homework Equations
Force of spring = -ks(stretch length)
arccosθ=adj/hyp
Net force=0
Force of spring + weight + tension = 0
The Attempt at a Solution
Force of spring = -185(.15)
Force of spring = -27.75 N
arccosθ=8/15
θ=57.77
Force of spring vector = <14.8, -24.47, 0> N
Weight = <0, -5.488,0> N
I don't know what to do from here
