2. In the figure below the particle P is in uniform circular motion. The motion is centered on the origin of an xy coordinate system.(adsbygoogle = window.adsbygoogle || []).push({});

(a) At what values of [tex]\vartheta[/tex] is the vertical component r[tex]_{y}[/tex] of the position vector greatest in magnitude?

(b) At what values of [tex]\vartheta[/tex] is the vertical component v[tex]_{y}[/tex] of the particle’s velocity greatest in magnitude?

(c) At what values of [tex]\vartheta[/tex] is the vertical component a[tex]_{y}[/tex] of the particle’s acceleration greatest in magnitude?

a. How can radius have a vertical component? It's just a distance or would it be a displacement?

b. Isn't velocity always tangential to the circle so how would there be a y component? Or does he just mean when it points in the y direction like at zero and 180 degrees?

c. Would it be 90 degrees and 270 because it only has a vertical component?

Any help would be appreciated
