(a) Show that the speed of the particle is (b) Use a graphing utility in parametric mode
Chapter 12, Problem 46(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.
(a) Show that the speed of the particle is \(b \omega\).
(b) Use a graphing utility in parametric mode to graph the circle for b = 6. Try different values of \(\omega\). Does the graphing utility draw the circle faster for greater values of \(\omega\)?
Text Transcription:
r(t)=b cos omega t i + b sin omega t j
omega=du/dt
b omega
