2 cars have a head on collision. (One coming from the left side straight on and the other coming from the right side straight on)

Car #1 from the left side is a smaller 952.5 kg Mitsubishi and car #2 from the right is a larger 1905.1 kg Toyota. Both cars are traveling 50 mph or 22.35 meter per second. What is the momentum impulse and acceleration for both cars.

I'm trying to prove that the larger car is safer, but I'm confused on calculations. Since I came up with this problem, please add any theoretical realistic missing values that may be needed to solve the problem.

Thank you so much this would be a big help if you could find the momentum impulse and acceleration with work/explanation.
