Rocket Forces Problem

🚀🌍 Forces Problem Tutorial: Landing on Earth! 🔍 Problem: A small rocket with mass 20.0 kg is moving in free fall toward the earth. Air resistance can be neglected. When the rocket is 80.0 m above the surface of the earth, it is moving downward with a speed of 30.0 m/s. At that instant the rocket engines start to fire and produce a constant upward force F on the rocket. Assume the change in the rocket’s mass is negligible. What is the value of F if the rocket’s speed becomes zero just as it reaches the surface of the earth, for a soft landing? 📚 Resources: University Physics with Modern Physics (14th Edition) by Young, Hugh D.; Freedman, Roger A.
