Show that for a free particle, a particle with momentum ~k (in a momentum eigenstate) is also an energy eigenstate, and compute its energy.

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.
