A particle of mass m moves in one dimension. Its potential energy is given by U(x) = -Voe-22/22 where U, and a are constants. (a) Draw an energy diagram showing the potential energy U(). Choose some value for the total mechanical energy E such that -U, < E < 0. Mark the kinetic energy, the potential energy and the total energy for the particle at some point of your choosing. (b) Find the force on the particle as a function...

Suppose we have a single particle moving in one dimension whose potential energy as a function of xx is U(x)U(x). Show (using the chain rule and the relationship F(x)=−U′(x)F(x)=−U′(x)) dEtotal/dt=0 , Conservation of Energy, for this system.
momentump,-hk (in one dimension) is in a region of space x<0 with potential function V-0. What is its energy? b) At x-0 the electron runs into a region of lower potential energy (V , rite down the form for the wavefunction of this electron. Vo <0). What is its new momentum? c) Set up the equations one would solve to find the probability that the electron gets reflected at x-0. (And explain where those equations came from.) Note that you're...
Using the mathematical expression of a traveling wave, determine the wave speed, and the speed of the medium. Please explain in simplest terms and give an example using units given.
2. If one dimension, if we have a potential energy function U(x) along with initial values for x and v, we can determine x and v for all subsequent times. A) Explain why this works. B) There's actually an exception to this think about starting at the top of a hill), why does your reasoning for A) no longer apply?
A particle undergoes simple harmonic motion (SHM) in one dimension. The r coordinate of the particle as a function of time is r(t)Aco() where A is the called the amptde" and w is called the "angular frequency." The motion is periodic with a period T given by Many physical systems are described by simple harmonic motion. Later in this course we will see, for example, that SHM describes the motion of a particle attached to an ideal spring. (a) What...
