See attached file. Definition 1: The linear momentum, vector p, of an object is its mass, m, times its velocity, vector v. Definition 2: The angular momentum, vector L, of an object about an axis, is defined as the cross product of the position, vector R, relative to the axis, and its linear momentum, vector p. Definition 3
A particle of mass 50g moves under an attractive central force of magnitude 4r^3 dynes. The angular momentum is equal to l,000 g*cm/s. a) Find the effective potential energy. b) Indicate on a sketch of the effective potential the total energy for circular motion. c) The radius of the particle's orbit varies between ro an
Mass m is attached to a post with radius R by a string. Initially, the mass is a distance r from the center of the post and is moving tangentially with a speed Vo. In case (a) the string passes through a hole in the center of the post at the top. The string is gradually shortened by drawing it through the hole. Case (b) the spri
Rotational and Angular Speed: a) what is the speed of the person with respect to the Earth? b)How much work did the person do in bringing the turn-table up to speed?
A turn-table on a frictionless vertical axis has a radius of 1.5 m and a moment of rotational inertia of 150 kgm^2. It is at rest until a 75 kg person who had been standing still (and who can be treated as a point), begins to walk around the rim at a speed of 2.0 m/s with respect to the turn-table. a) what is the speed of the p
A .015 kg coin of diameter .013 m is spinning at 9 rev/s about a vertical diameter at a fixed point on a tabletop. a) If the coin spins about a vertical diameter at 9 rev/s while its center of mass travels in a straight line across the tabletop at .05 m/s, what is the angular momentum of the coin about a point on the line of mot

If a rigid homogeneous rectangular crate of mass m and height h slides on its base of w, while traveling a velocity v, it stikes a low, immovable curb. What is the angular velocity of the crate immediately after the impact, in terms of m,w,h,v; and under what condition (in m,w,h,v) will the crate fall over on its side?
Show that angular momentum quantization of an electron in a hydrogen atom is the necessary consequence of de Broglie's matter wave concept.
