A red toy car has an acceleration of 4.00 m/s², whereas a blue toy car has an acceleration of 2.00 m/s². You start the blue car from rest down a track of length 9.00 m. How much time must you wait before starting the red car from rest, such that the two cars reach the end of the track at the same time?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
