Show that the magnitude of the acceleration vector is
Chapter 12, Problem 48(choose chapter or problem)
Circular Motion In Exercises 45-48, consider a particle moving on a circular path of radius b described by \(r(t)=b \cos \omega t \mathrm{i}+b \sin \omega t \mathrm{j}\), where \(\omega=d u / d t\) is the constant angular velocity.
Show that the magnitude of the acceleration vector is \(b \omega^{2}\).
Text Transcription:
r(t)=b cos omega t i + b sin omega t j
omega=du/dt
b omega^2
