In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an \( x \) axis. At time \( t=0 \), the red car is at \( x_{p}=0 \) and the green car is at \( x_{\mathrm{g}}=216 \mathrm{~m} \). If the red car has a constant velocity of \( 27.0 \mathrm{~km} / \mathrm{h} \), the cars pass each other at \( x=44.5 \mathrm{~m} \). On the other hand, if the red car has a constant velocity of \( 54.0 \mathrm{~km} / \mathrm{h} \), they pass each other at \( x=76.4 \mathrm{~m} \). What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs,
