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

50mph because ...........................................

2 cars of equal mass that crash head on at 50 mph
can also be looked at as one car going 100mph crashing
into a stationary car of the same mass.

When that happens the force of the collision at 100mph is
cut in two and split equally between two cars.
