A particle is constrained to move along the positive x-axis under the influence of a force whose potential energy is U(x) = U_0(2 cos x/a - x/a) where U_0 and a are positive constants. Plot U versus x. A simple hand sketch is fine. Find the equilibrium point(s). For each equilibrium point, determine whether the equilibrium is stable or unstable.

A 1kg particle is in a region where the potential energy can be represented by the function U(x) = x 2 − 5, where using x in meters will give you U in J. The particle is released from rest at x = 2.0m. (a)In which direction does it move? Why? (b)What is its velocity when it has moved 2m? (c)Where does the particle first come to rest after you release it? (d)Describe the long-term motion of the particle.

The figure shows a plot of potential energy U versus
position x of a 0.280 kg particle that can travel only
along an x axis under the influence of a conservative
force. The graph has these values: UA
= 9.00 J, UC = 20.0 J and
UD = 24.0 J. The particle is released
at the point where U forms a “potential hill” of “height”
UB = 12.0 J, with kinetic energy 5.00
