two forces f1 and f2 act on a 5.00-kg object.if f1=20.0N and f2=15.0N find the accelerations
Are the forces acting on the object from the same direction?
|dw:1349487144650:dw|f1Perpendicular to the f2 Form a right angle 90
F=MA....but the F needs to be broken up into vectors to find combination of the forces.
This is a simple one...rather than type it all out, page 1 of this document explains it very well an includes images: http://www.mash.dept.shef.ac.uk/Resources/em15forceasvector.pdf
calculate resultant force first,,that will be whole root of 15 squre plus 20 square in newton,that gained value should be divided by mass 5kg,thats it
