How Do You Calculate the Magnitude and Direction of Coplanar Forces?

AI Thread Summary
To calculate the magnitude and direction of the three coplanar forces, first determine the east/west and north/south components for each force vector. The components are then summed separately to obtain total forces in each direction. The overall magnitude can be calculated using the Pythagorean theorem, while the direction can be found using the inverse tangent function. Detailed step-by-step guidance is essential for those new to physics concepts. Understanding these calculations is crucial for solving problems involving coplanar forces.

Homework Statement



Find the magnitude and direction of 3 coplanar forces of:
40N 45 degrees east of south
10N west
70N 35 degrees east of north


This is all new to me so anyone that can show me and hopefully explain how I can get the answer would be great.

Find the East/west and north/south components for each vector.
Add them separately to get totals in each direction.
Combine them using pythagorean thm for magnitude and inverse tan for angle.
 
Thanks for the reply, but physics is totally new to me and I've been online to try to teach myself but I'm having no luck...can you be more specific.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
