Question
A particle of mass m is constrained to lie along a frictionless, horizontal plane subject to
a force given by the expression F(x) = -kx. It is projected from x = 0 to the right along
the positive x direction with initial kinetic energy To 1/2 kA". k and A are positive con-
stants. Find (a) the potential energy function V(x) for this force; (b) the kinetic energy,
and (c) the total energy of the particle as a function of its position. (d) Find the turning
points of the motion. (e) Sketch the potential, kinetic, and total energy functions.
(Optional: Use Mathcad or Mathematica to plot these functions. Set k and A each equal
