Question

( gamma_{2} quad cos omega t hat{x} quad+sin omega t hat{y} )
( overrightarrow{0}=frac{d x}{d t} )
( [vec{v}=infty-w sin w t hat{t}+w cos omega t hat{j}] )
( vec{a}=frac{d v}{d 1} )
( =-w^{2} cos w t hat{i}=w^{2} sin w t )
( frac{1}{a}=frac{-w^{2}}{-w^{2} gamma}left(cos w t^{-2}+sin w+hat{j}right) )
