SUMMARY

The discussion focuses on solving vector and force problems in physics, specifically addressing a tug-o-war scenario where women exert a total force of 3N against men's forces of 2.9N, resulting in a net force of 0.1N favoring the women. Additionally, it covers a tubing problem where a paddler travels downstream at a combined velocity of 11KM/HR, needing approximately 49 minutes to reach a car 9KM away. The conversation also includes calculating resultant displacement after a series of movements and determining the velocity components of an airplane flying at 625KM/HR at a compass heading of 330 degrees. Diagrams are emphasized as essential tools for visualizing and solving these problems.

PREREQUISITES
  • Understanding of basic vector addition and subtraction
  • Familiarity with velocity and speed concepts
  • Knowledge of trigonometric functions for vector components
  • Ability to interpret and create diagrams for physics problems
NEXT STEPS
  • Study vector addition and subtraction techniques in physics
  • Learn how to calculate resultant velocities in moving objects
  • Explore trigonometric functions for resolving vector components
  • Practice drawing and interpreting diagrams for complex motion problems
USEFUL FOR

Students studying physics, educators teaching vector mechanics, and anyone looking to improve their problem-solving skills in force and motion scenarios.

It's Trig and Vector Review For Physics
I Haven't Learned How To Solve Vector Problems Yet In Math
I Tried Looking In The Math Book But I Still Don't Understand
And We Aren't Given A Physics Book
Please Help; You Don't Have To Give The Answer Just Steps To Help Solve It

7) The women decide to have a tug-o-war contest with the men. Two representatives are chosen from each. Each woman pulls with a force of 1.5N. One of the men can pull with a force of 2N and the other with 0.9N.
A)What is the total force exerted by the women?
B)By the men?
C)What is the resultant force?

8)While tubing you realize that you are going to be late for a date. You paddle downstream at a velocity of 6KM/HR and the rive flows at 5KM/HR. If your car is 9KM downstream how many minutes will it take you to reach it?
(I found that 6KM/HR=1.0KM/MIN and 5KM/HR=0.8KM/MIN)

9) While trying to intercept the love of his life Jon traveled 10Meters north, 5Meters west, 14Meters south, and 2Meters east. How far and in what direction did he end up with reference to his original position?

10)An airplane flies with a velocity of 625KM/HR at a compass heading 330 (Degrees) What are the components of its velocity in a southerly and easterly direction?

HI,
In all the questions drawing a diagram will help.
7 is adding and subtracting forces in 1 dimension
8 is similar to 7 but with speeds rather than forces
9 draw a diagram to scale
10 draw a diagram and use some trig

Note in question 8 that your wrong with the speed per minute 6km/hr is not same as 1km/min otherwise it would only take 6mins to do 6km not 1 hour.


hope this helps
