Ok, thanks for mentioning that. Thank you for all of your help! Now I actually understand how work with these equations!
Calculating Net Force: Solving for Unknowns in Vector Addition
Click For Summary
SUMMARY
The discussion focuses on calculating the net force using vector addition, specifically applying the law of cosines and the sine rule. The participants utilize the formula \(c^2 = a^2 + b^2 - 2ab \cos C\) to find the resultant force and its direction. The final calculations yield a net force of approximately 33N at an angle of 71 degrees from the horizontal. The importance of resolving forces into components and understanding vector direction is emphasized throughout the conversation.
