I don't think you all are using the F=ma formula correctly. that does not really measure the force of impact with another object. Instead it measures the amount of force needed to accelerate that mass to a certain speed.
For example a train traveling 100MPH but with zero acceleration is going to do a lot more damage to you than the same train going 5MPH but accelerating at a rate of 1 foot/second squared.
