A rocket moves upward starting from rest with an acceleration of 20 m/s^2 for 5 s. It runs out of fuel at the end of this 5 s and continues to move upward, acted upon only by gravity. How high does it rise? Find the velocity of the rocket just before it hits the ground and how long it is in the air?

4. A rocket was traveling straight upward at a constant velocity vo- 80 m/s before it runs out of fucl at a height h- 8000 m. The rocket then continues its vertical motion reaching its maximum height at point A, before turning down in a free fall motion back to ground. (Take g -10 m/s) (a) Determine the maximum height reached by the rocket with respect to O (b) How long - from O- does it take the rocket to...
