SUMMARY

The discussion focuses on calculating deceleration due to air resistance and gravity for a rocket with a top velocity of 14.16 m/s at a 45-degree angle after engine shutdown. The complexities of air resistance are acknowledged, noting that it is often overlooked in educational contexts. The recommended approach involves separating the horizontal and vertical components of motion, similar to solving projectile motion problems in physics.

PREREQUISITES
  • Understanding of basic physics concepts, specifically projectile motion.
  • Familiarity with vector decomposition in two-dimensional motion.
  • Knowledge of forces acting on an object, including gravity and air resistance.
  • Basic mathematical skills for calculating deceleration and resolving components.
NEXT STEPS
  • Research the effects of air resistance on projectile motion using differential equations.
  • Study the principles of vector decomposition in physics to analyze motion at angles.
  • Explore numerical methods for simulating deceleration in real-world scenarios.
  • Learn about the drag coefficient and its role in calculating air resistance for various shapes.
USEFUL FOR

Physics students, aerospace engineers, and anyone interested in understanding the dynamics of motion under the influence of gravity and air resistance.

I have a rocket with a top velocity of 14.16 m/s when the engine stops.

How do i calculate its deceleration based on air resistance and gravity if it is flying at approximatly 45 degress?

There is no easy way to deal with air resistance. It is ignored in most courses.
Also, we usually simplify matters by saying the engine burns for so small a time it is effectively zero.

So, it is just another baseball problem. Do the horizontal and vertical parts separately.
