Physics

After 500 years of drifting in space and a brief visit on boardthe flagship Draconia, Buck Rogers headed to the FederalDirectorate of Earth in his spacecraft. His descent consisted ofthe following stages. Assume that each stage followed immediatelyafter the preceding stage and that the acceleration during eachstage was constant. Stage A: Friction with the atmosphere reducedthe speed from 19,500 km/h to 1700 km/h in 4.0 min. Stage B: Aparachute then opened to slow it down to 340 km/h in 100 s. StageC: Retro rockets then fired to reduce its speed to zero over adistance of 75 m. (a) Calculate the spacecraft’s acceleration (m/s2) during each stage. (b) What total distance (km) did thespacecraft travel in each stage
