A red car and a green car are traveling along a straight road in the same direction. The red car's position is given by x(t)=t3 and the green car is accelerating at a constant rate. At time t = 0, the green car is 132 m ahead of the red car. At t = 2 s, the red car reaches the same speed as the green car, and at t = 6 s, the red car catches up to the green car. What is the initial velocity and acceleration of the green car?
