On page 126 it is implied that if a person collides with two objects, the object with the most momentum will do that person the most harm. This is nonsense. I am likely to survive being hit by a car at 10 mph, but I will certainly be killed if I'm hit by a 1 kg projectile travelling at 2000 m/s, even though it has less than half the momentum.
