- Aircraft ( P ) takes off at ( A ) with a velocity ( v_{0} ) of ( 250 mathrm{kmh} ) and climbs in the vertical ( y^{prime} ) - ( z^{prime} ) plane at the constant ( 15^{circ} ) angle with an acceleration along its flight path of ( 0.8 mathrm{~m} / mathrm{s}^{2} ).- Flight progress is monitored by radar at point ( O ). Resolve the velocity of ( P ) into cylindrical-coordinate components 60 seconds after takeoff and find ( r^{prime}, theta ), and ( z ) for that instant.Hint: Use cylindrical coordinate system- ( boldsymbol{v}=dot{r} mathbf{e}_{r}+r dot{theta} mathbf{e}_{theta}+dot{z} mathbf{k} )21
