The answer is "A". 100 mph, because

E1=E2 when two cars hit head on which means each car would absorb 50 kmh of
kinetic energy BUT when a car hits a wall
E1 is divided in 1/2, 1/2 going to the wall and 1/2 to the car. It's all in
the wording of the question.

I'm bored so will put forward this one to see what happens:

2 cars of equal mass crash head on at 50 mph. Both drivers will feel
an impact equal to crashing into a solid object at:
a. 100 mph
b. 50 mph
c. Other
