a small weather rocket weighs 20.5 N. The rocket is carried up into the air by a balloon. The rocket is released from the balloon and fired. What is the acceleration of the rocket if an upward force of 25 N is applied?

Net force = force up - force down.

force down is its weight, and force up is 25N. Once you know net force, you can get acceleration.
