A model rocket has a constant upward acceleration of 40.0m/(s^2) while its engine is running. The rocket is fired vertically, and the engine runs for 2.59s before the fuel is used up. After the engine stops, the rocket is in free fall. The motion of the rocket is purely up and down.
What is the maximum height that the rocket reaches?
What will b e the speed of the rocket just before it heats the ground?
Yes I have looked through the forums for similar posts similar to my question and I have found one https://www.physicsforums.com/showthread.php?t=44459&highlight=rocket
However that one does include a given initial velocity and my problem does not. I do not know where to start.
Thank you very much for your help.
