A particle of mass m is acted on by a conservative force scalar potential is Ax^2/2 with A>0 constant. (a) Write the Lagrange for the system, drive the equations of motion using Lagrange's equation, and name all conserved quantities.
Compare the shift in frequency if a 1750 Hz source is moving toward you at 15m/s versus you moving toward it at 15 m/s. Are the two frequencies exactly the same? Are they close? (b) Repeat the calculation for 150 m/s and then again (c) for 300 m/s. W..
