a 2000kg rocket has a rocket motor thast generates 3.0 x 10^5 N of thrust.
What is the rockets initial upward acceleration ?
( I got 140ms^2)???? don't know if its right
and then it says
at an altitude of 5000m the rockets acceleration has increased to 6.0m/s^2. What is the mass of fuel has it burned ?
