Colonel John Stapp led the U. S. Air Force Aero Medical Laboratory’s research into the effects of high accelerations on the human body. On Stapp’s final run, he rode a rocket-propelled sled that reached a speed of 284.4 m/s (632 mph) and then stopped with the aid of water brakes in 1.2 seconds. Stapp was barely conscious and lost his vision for several days, but recovered. Determine his acceleration while stopping and the distance he travelled while stopping.

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

is in the form atp or adenosine triphosphate

answer: that would be cheating

explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
