Problem 92

A police radar gun operates at a frequency of 10.5 GHz.The offi cer, sitting in a patrol car at rest by the highway,directs the radar beam toward a speeding car traveling80 mph directly away from the patrol car. What is thefrequency shift of the refl ected beam, relative to theoriginal radar beam?

Step-by-Step Solution:
Step 1 of 3

Chapter 17 Notes Sec. 1:  Newton’s First Law: If no force acts on a body, then  the body’s velocity cannot change  Newton’s Second Law: F = ma  Newton’s laws of motion allow us to analyze many kinds of motion  Conservation of energy Ki +Ui = Kf +U f  In an isolated system where only conservative forces  cause energy changes, the kinetic energy and potential  energy can change, but their sum cannot change  Gravitational and electro-magnetic forces: this what we experience!!! Frictional force, spring force, normal force, tension force in a string, aerodynamic force … are results of electromagnetic force Sec. 2  An electric charge has a magnitude and sign.  It is either positive or negative. Electron has negative electric charge. Proton has positive e
