Finding Resultant Force: Calculation and Explanation

Click For Summary
SUMMARY

The discussion centers on calculating the resultant force acting on a parachutist experiencing three forces: an upward force of 500N, a downward force of 1000N, and a wind force of 300N at a 45-degree angle upwards. Participants emphasize the importance of resolving the wind force into its horizontal and vertical components before summing the forces. The correct resultant force is determined using the Pythagorean theorem and trigonometric functions, with the final answer being approximately 357.6N. A force diagram is essential for visualizing the forces and their components.

PREREQUISITES
  • Understanding of vector resolution and components
  • Familiarity with the Pythagorean theorem
  • Basic knowledge of trigonometric functions (sine, cosine)
  • Ability to draw and interpret force diagrams
NEXT STEPS
  • Learn how to resolve forces into their components using trigonometry
  • Study the Pythagorean theorem application in physics problems
  • Explore vector addition techniques for multiple forces
  • Understand the laws of sine and cosine in the context of triangle formation
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and force analysis, as well as anyone preparing for tests involving vector resolution and resultant force calculations.

angle between the resultant and the wind (on the left side of resultant). If u go in the vector adddition site which u gave me the first one http://physics.bu.edu/~duffy/java/VectorAdd.html
in this site the angle between green and red in the question.Hopefully u got it and can explain me.

This sounds reasonable, that the resultant and wind vectors are 81 degrees apart.
