Newton's Law of Motion Problem, HELP :'(

Click For Summary
SUMMARY

The discussion focuses on a physics problem involving Newton's Laws of Motion, specifically analyzing the forces acting on an 8-passenger Learjet. The gravitational force acting on the plane is 66,000 N downward, while the forward thrust from the engines is 13,000 N westward. To determine the upward lift force and the force due to air resistance, one must assess the vertical and horizontal forces acting on the plane, considering that it travels at a constant velocity of 640 km/hr, indicating no acceleration in either direction.

PREREQUISITES
  • Understanding of Newton's Laws of Motion
  • Basic knowledge of force vectors
  • Familiarity with concepts of lift and drag in aerodynamics
  • Ability to perform vector addition and equilibrium analysis
NEXT STEPS
  • Study the principles of lift in aviation, focusing on Bernoulli's principle
  • Learn about drag forces and their calculation in aerodynamics
  • Review vector resolution techniques for analyzing forces
  • Explore real-world applications of Newton's Laws in aviation dynamics
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and aerodynamics, as well as educators seeking to explain force interactions in aviation contexts.

Homework Statement


Assume a 8-passenger learjet has a force of gravity of 66000 N [down] acting on it as it travels at a constant velocity of 640 km/hr [W]. if the forward thrust provided by the engines is 13000 N [W], determine:

a - the upward life force on the plane
b - the force due to air resistance on the plane


Homework Equations





The Attempt at a Solution


i have absolutely no clue on how to even begin, I am so lost. please help, thanks.

1. Is the plane accelerating the vertical direction (up or down)?
2. What does this imply about the total vertical force acting on it?

3. Is the plane accelerating in the horizontal direction?
4. What does this imply about the total horizontal force acting on it?
