A rocket is fired vertically and ascends with a constant vertical acceleration of 20.0 m/s^2 for 2.00 seconds. Its fuel is then used up and it continues as a free object. What is the maximum altitude reached?
The Attempt at a Solution
I usually start off making an x vs. t, v vs. t, and an a vs. graph in order to get a variable list so I can plug into the equation and solve but I'm thrown off by how to even begin the problem when it says it runs out of fuel and continues as a free object.
