Due April 19th, 2019 1. (3 pts) Consider two particles of mass mi and m2 (in one dimension) that interact via a potential that depends only on the dstance between the particles V(l 2), so that the Hamiltonian is Acting on a two-particle wave function the translation operator would be (a) Show that the translation operator can be written as where P- p p2 is the total momentum operator of the syste (b) Show that the total momentum is conserved...
1. The wavefunction corresponding to Im> energy and angular momentum eigenstate of a particle rotating in a ring for m-l and m--1 are, respectively N2T where ? is the angular position of the particle relative to thex axis (see slide 15 of lecture 74a). (a) show that the probability density does not depend on 0. (b) Show that P,(o)-sin() where p, (0) rticle in the quantum state V, (d) p, (0) obviously resembles one of the orbitals of the is...
Tutorial: Angular Momentum and Torque III. Angular Momentum The angular momentum of a point particle is defined by: L = ixp. Here, is a vector that points from the point of rotation (or point around which the angular momentum is calculated) to the location of the particle and p = mb is the linear momentum of the particle. A Your little brother Joey is playing with his toy airplane. The airplane is tied to a string and its motor makes...
5. The figures on the right show a disk with radius, a = 0.20 m, and mass, M = 0.80 kg, resting on a frictionless table. One particle with mass, m1-M/4, with velocity, v- 4 m/s, slides along the stable, and collides with the disk at the point shown. A second particle with mass, m2, moving with velocity v2-4v collides with the disk at the point shown. The two masses collide with the disk at the same time, and after...
At one instant, the center of mass of a system of two particles is located on the x-axis at x = 2.0 m and has a velocity of (5.0 m/s ) i^. One of the particles is at the origin. The other particle has a mass of 0.10 kg and is at rest on the x-axis at x = 8.0 m. What is the mass of the particle at the origin? Calculate the total momentum of this system. What is...
1. What is the angular momentum of a 0.240-kg ball rotating on the end of a thin string in a circle of radius 1.35 m at an angular speed of 15.0 rad/s ? 2. A diver can reduce her moment of inertia by a factor of about 4.0 when changing from the straight position to the tuck position. If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed (rev/s) when in the...
