A rocket blasts off and moves straight upward from the launch pad with constant acceleration. After 2.6 s the rocket is at a height of 80.0 m. (a) What is the acceleration of the rocket? ______m/s2 (b) What is its speed at this time? ______m/s Hello, I have been stumped on this question all day. I have no clue on how to do this problem, I have tried 80/2.6/2.6 to get the average acceleration squared, but that was not the correct answer. Can anybody please explain how to do this?
