A picture of a rocket. There is a free body diagram to the right of the rocket with 2 forces. The force upward is labeled F Subscript gases Baseline = 9,452 N. The second vector is pointing down, labeled F Subscript rocket Baseline = negative 9,452 N. Both vectors are the same length. Based on the free-body diagram, the net force acting on this firework is N.
