A Sаturn V rоcket's pоwerful bоosters аre cаpable of producing a powerful upward acceleration. During a test run of a similar rocket, NASA launches a prototype vertically upward on a calm day (no wind), burning fuel and producing a roughly constant acceleration until it reaches an upward speed of 722 m/s. After the engines shut off, the rocket begins to freefall, eventually coming back down to the earth after reaching a maximum height of 123 km. Ignoring air resistance, a) How far from the ground was the rocket when its boosters turned off and it began to freefall? b) What was the prototype rocket's upward acceleration while its boosters were firing? c) For how long were the boosters firing? d) For what total time is the rocket in the air before striking the ground?
