A particle moves in one dimension (the X-axis), with potential energy given by the function U(x), where K and Xo are positive constants. U(x) = Kx^2 + C T0
a) Find the corresponding force function F(x): Remember, the force can be found by taking the derivative of the potential energy: F(x) = dU/dx
b) The equilibrium positions of the particle are positions where the force on the particle goes to zero. Find the equilibrium position of the particle.
