A article is in uniform circular motion about the origin of an xy coordinate system, moving clockwise with a period of 6.80 s. At one instant, its position vector (from the origin) is r Overscript right-arrow EndScripts equals left-parenthesis 4.30 m right-parenthesis i Overscript ̂ EndScripts minus left-parenthesis 2.10 m right-parenthesis j Overscript ̂ EndScripts. At that instant, what is its velocity in unit-vector notation?

A particle is in uniform circular motion about the origin of an xy coordinate system,

moving clockwise with a period of 6.80 s. 

At one instant, its position vector (from the origin) is r =(4.30 m) i - (2.10 m)j. 

At that instant, what is its velocity in unit-vector notation?
