1. The problem statement, all variables and given/known data A 200kg weather rocket is loaded with 100kg of fuel and fired straight up. It accelerates upward at 35m/s^2 for 32 s, then runs out of fuel. Ignore any air resistance effects. What is the rocket's maximum altitude? How long is the rocket in the air? 2. Relevant equations Vf^2=Vi^2-2as Vf=Vi+at 3. The attempt at a solution Vf=0+(35)(32) Vf=1120m/s 1120=0+2(35)s 1234400=70s s=133.865m I think I'm supposed to add the weight in, but I'm not sure on how to do that.
