... Use F = Δp/Δt = 100 kg m/s (west)/ (.01 sec) = 1E4 N (West). Which corresponds to about 1 ton. This feels about the same as having a car sitting on your head... If there's an airbag (or seatbelt), you can increase the time you take to accelerate a lot, perhaps a factor of 10 or more. That's all you ...
