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?
The Attempt at a Solution
I think I'm supposed to add the weight in, but I'm not sure on how to do that.
