Answer

$10.5\ m$

Work Step by Step

The angle toward the $+x^{\prime}$ axis is $18.0^{o}$ less than before, so $\theta^{\prime}=56.0^{o}-18.0^{o}=38.0^{o}$ The magnitude of $\vec{a}$ remains the same. Given the magnitude and new angle (in the new coordinate system), using (3-5), $a_{y}^{\prime}=a\sin\theta^{\prime} =(17.0m)(\sin 38.0^{o})=10.5\ m$
