Problem

0.50\,\text{kg}

cart attached to a horizontal spring experiences a net force

F(x)= -12x

(in newtons) when the spring is the only horizontal force. When a constant

2.0\,\text{N}

fan force blowing in the

+x

direction is turned on, the net force becomes

F_{\text{net}}(x)= -12x + 2.0

, with

x

in meters. What is the new equilibrium position of the cart? a)

0.17\,\text{m}

in the

-x

direction b)

0.083\,\text{m}

in the

+x

direction c)

0.33\,\text{m}

in the

+x

direction d)

0.17\,\text{m}

in the

+x

direction
