a 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. it accelerates upward at 30.0 m/s2 for 30.0 s, then runs out of fuel. ignore any air resistance effects.
a) What is the rocket's maximum altitude?b) How long is the rocket in the air?c) Draw a velocity vs. time graph for the rocket from lift-off until it hits the ground.
