Combustion Engine

realization that this was not the case, based on investigations by Karl Wilhem Scheele, in 1772, Joseph Priestly in 1774, Lavoisier in 1779, and Cavendish, in 1784. These scientists were all investigating the process of combustion; at that time, it was widely held that combustion resulted in the liberation of a separate entity into the air called phlogiston, derived from burned material. The change in state of liquid water to a vapor requires energy. This energy is needed to overcome the…

the engines cut off. y − y0 = 525 m , a y = +2.25 m/s 2 , v0 y = 0 . 2 2 v y = v0 y + 2a y ( y − y0 ) gives v y = 2(2.25 m/s 2 )(525 m) = 48.6 m/s . Now consider the motion from engine cut off to maximum height: y0 = 525 m , v0 y = +48.6 m/s , v y = 0 (at the 2 2 maximum height), a y = −9.80 m/s 2 . v y = v0 y + 2a y ( y − y0 ) gives y − y0 = 2 2 v y − v0 y 2a y = 0 − (48.6 m/s) 2 = 121 m and 2(−9.80 m/s 2 ) y = 121 m + 525 m = 646 m .
