Triangle ABC is an acute angled triangle. A line passing through the incenter of the triangle divides the triangle into two equal areas. If S is the perimeter of Δ ABC, then CD + CE = ??

in terms of S

I'm driving my car of mass 1000 kg at 100 km/hr when I accidentally hit the rear end of a truck of mass 5000 kg traveling in the same direction at 90 km/hr. My car and the truck lock together and move as a single object. Let F1 be the force the truck exerts on my car and let F2 be the force my car exerts on the truck. What is F1/F2 during the collision?Details and assumptionsYou may ignore friction and air resistance.The problem can be taken to be 1-d.F1 and F2 are not the magnitudes of the forces, remember, but the actual forces themselves.
is it 4.5?
