What will be the future of the rocket?

Method
  • Imagine a rocket launched from the earth. The distance of the rocket from the earth increases due to its initial speed.
  • The speed of the rocket decreases due to the force of gravity.
  • The gravitational force also goes on decreasing as the distance increases. Keeping both of these in mind, discuss the questions below.
Discussion
  • (a) If the effect of gravity becomes zero before the speed of the rocket becomes zero, what will be the future of the rocket?
  • (b) If the speed of the rocket becomes zero before the force of gravity becomes zero, what will be the future of the rocket?
  • (c) What will happen if the effect of gravity becomes exactly zero when the speed of the rocket becomes zero?
