PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

doomed but there are two important ones‚ we are a growing world‚ our population increases exponentially‚ how do we possibly think we can slow down CO2 when our population increases by a billion on average every 12 years. Now the reality is to feed 7 billion people it takes a lot of energy to do this‚ and the only reliable source and have been for many years are fossil fuels. The second issue is that it is the environment vs. the economy‚ at a point in time they were both striving on the same

Application Of Physics In Medicine Medical physics is generally speaking the application of physics concepts‚ theories and methods to medicine. A medical physics department may be based in either a hospital or a university. Clinical medical physicists are often found in Diagnostic and Interventional Radiology‚ Nuclear Medicine and Radiation Oncology. However‚ areas of specialty are widely varied in scope and breadth e.g.‚ clinical physiology‚ neurophysiology (Finland)‚ and audiology
