A rocket rises vertically from rest, with an acceleration of 3.2 m/s2until it runs out of fuel at an altitude of 1200m. After this point, its acceleration is that gravity in a downward direction. a. How long does it take for the rocket to run out of fuel?b. What is the rocket’s velocity when it reaches this point?c. How much total time does it take to reach maximum altitude?18 Worksheet Problems:d. What maximum altitude does the rocket reach?e. How much total time is it in the air?f. With what velocity does it strike the Earth?
