In Section 8.6, we considered a rocket fired in outer space where there is no air resistance
Question:
(a) How is Eq. (8.37) modified by the presence of the gravity force?
(b) Derive an expression for the acceleration a of the rocket, analogous to Eq. (8.39).
(c) What is the acceleration of the rocket in Example 8.15 (Section.8.6) if it is near the earth's surface rather than in outer space? You can ignore air resistance.
(d) Find the speed of the rocket in Example 8.16 (Section 8.6) after 90 s if the rocket is fired from the earth's surface rather than in outer space. You can ignore air resistance. How does your answer compare with the rocket speed calculated in Example 8.16?
