Problem text A vertical semicircular guide, with radius and without friction, is constrained to a platform that moves with constant acceleration along the horizontal direction (see figure). A point body of mass , initially...
Problem text Let us consider an object shaped as a parallelepiped and placed on a horizontal plane with friction (see figure). In particular, let us suppose that the object has a mass , a...
Solved problem A ball is tied to one end of a string. The other end of the string is held fixed. The ball is set moving around a vertical circumference without friction, and with...
A parabolic mirror is a mirror that has the shape of a rotating paraboloid. The latter one is a space surface of equation (see example in the figure below for ), obtained by rotating...
Today, we will study the motion of a skydiver with the aim to obtain its speed-time graph. For this purpose, we will use both a spreadsheet and the graphics of the didactic software GeoGebra. As...
Monte Carlo Study of Electron Spin Relaxation in n-type GaAs Bulk. The new field of semiconductor spintronics represents a possible direction towards the development of hybrid devices that could perform logic operations, communication and storage,...
