1. The problem statement, all variables and given/known data 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 xr = 0 and the green car is at xg = 223 m. If the red car has a constant velocity of 20.0 km/h, the cars pass each other at x = 43.1 m. On the other hand, if the red car has a constant velocity of 40.0 km/h, they pass each other atx = 76.9 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs. 2. Relevant equations 3. The attempt at a solution eq 1 = 179.9=Vo(7.75)+1/2a(7.75)^2 eq 2 = 146.1=Vo(6.92)+1/2a(6.92)^2 insert 2 to 1 Vo = 146.1-1/2a(6.92)/(6.92) 179.9=(146.1-1/2a(6.92)/(6.92))(7.75)+1/2a(7.75)^2 got a = 5.06 m/s^2 and vo as 3.60 is my answer right????
