A particle is created in a shower of particle decays. Its velocity is measured to a precision of 50 micrometers/second and its mass is inferred to be (exactly) 6.64×10−27 kg. What is the minimum uncertainty in our knowledge of the particle’s position? Explain.
2. A free particle (a particle that has zero potential energy) has mass 8 eV/c² and total energy
10 eV and is traveling to the right. At x = 0, the potential jumps from zero to Vo = 5 eV
and remains at this value for all positive x.
(a) In classical mechanics, what happens to the particle when it reaches x = 0?
(b) What is the wavenumber of the quantum particle in the region x > 0?
(c) Find the reflection coefficient R and the transmission coefficient T for the quantum
particle.
(d) If one million particles with this same momentum and energy are incident on this poten-
tial step, how many particles are expected to continue along in the positive x direction?
How does this compare with the classical prediction?
A quantum particle of mass m is placed in a one-dimensional box of length L. Assume the box is so small that the particle’s motion is relativistic and K = p2/2m is not valid. (a) Derive an expression for the kinetic energy levels of theparticle. (b) Assume the particle is an electron in a box of length L = 1.00 × 10-12 m. Find its lowest possible kinetic energy.

Everyone knows the joke of the policeman stopping Heisenberg, who was speeding, and ask him: "Do you know how fast you were going?" Then Heisen- ber replies: "No, but I know exactly where I am." Now let's investigate the truth behind this story in more detail. Heisenberg was actually late for his quantum mechanics class and was stopped by a police officer for speeding his Merc, weighing 4000 kg, at v = 200 km/h in downtown Leipzig (Germany). The radar detector measured the speed us- ing the Doppler effect, with an uncertainty of 1%. With what fundamental accuracy could the officer have located Heisenberg's position, if this was mea- sured simultaneously with the speed?

The alpha particle, whose mass is m = 6.64 x 10^(-27) kg, remains attached to the nucleus due to a strong interaction with the other nuclear constituents (nucleons) which overcomes the electrostatic repulsion between them, resulting in a graph of potential energy shown in figure A, where R is the range of the strong force and is of the order of the nuclear radius. However, note that there may be states for the alpha particle with energy E > 0 that can “tunnel” the Coulomb potential barrier. Consider a one-dimensional approximation for the potential energy well of an alpha particle in a 15 fm wide Uranium core (equivalent to the core diameter), in which the Coulomb barrier was modeled as a 20 fm wide rectangular barrier and 30 MeV high (see figure B).
