Question
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 = 213 m. If the red car has a constant velocity of27.0 km/h, the cars pass each other at x = 43.8 m. On the other hand, if the red car has a constant velocity of 54.0 km/h, they pass each other at x = 76.2 m. What are (a) the initial velocity (in km/h) and (b) the (constant) acceleration (in m/s2) of the green car? Include the signs.

What are (a) the initial velocity (in km/h) and (b) the (constant) acceleration (in m/s2) of the green car? Include the signs.Explanation / Answer
1 km/h = 10m/36s
27 km/hr = 7.5 m/s
54km/hr= 15m/s
the time when they pass each other
43.8 /7.5 = 5.84 secs
red car = 7.5 (5.84)
green car = 0.5(a)(5.84)
