A world's land speed record was set by Colonel John P. Stapp when in March 1954 he rode a rocket-propelled sled that moved along a track at 1020 km/h. He and the sled were brought to a stop in 1.4 seconds. In terms of g, what acceleration did he experience while stopping?

Not sure if this is the run in question, but peak decelaration (as opposed to average, which would indeed be in the order of 20 G) he ever experienced was 46.2 G.
Col Stapp suffered damage to his eyes from all that abse, and his vision was permanently affected.

i think which you've gotten 2 styles of graphs, the 1st style of graph is parabolic. occasion I drop an apple off of a tree and till it hits the floor it is in consistent acceleration, and its velocity is increasing. interior the 2d case, velocity may be fixed yet you have consistent acceleration. occasion a satellite tv for pc orbiting the earth. (assume the earth is the middle of the universe because of the fact in case you do no longer then you definately would desire to account the orbit of the earth around the solar, the solar around the middle of the milklyway galaxy, and on and on. i'm hoping this permits

acceleration is chage in speed per unit time... so his speed changed by 1020km/h / 1.4 seconds... get the units right (I recommend meters per second), and you have the correct answer.

I also get 20.65g. Must be right. (I'm just trying to accumulate points jumping on someone else's bandwagon.)
