Homework Statement



Find the magnitude and direction of 4 concurrent coplanar forces:

10N 32 degrees east of north
35N 50 degrees east of north
25N 72 degrees east of north
85N 40 degrees east of south


Any help would be greatly appreciated.
 
Physics news on Phys.org
Split the forces into X and y components then solve
 
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.
 
choose X and Y axis along north, south direction
Find X,Y components like in the pic.

find the net force of vector components along X axis by by adding vectors in same direction and subtracting the ones in opposite direction.
do same for Y axis.

Then find the net force of X and Y forces using this: sqrt(FX + FY)

Of course you mean sqrt(F2X + F2Y).
 
Oh yes!
my bad
