الله يوفقكم في باب kinetic energy and work
Three forcec applied to trunk moved left ward by 3 m over frictional floor the force magnitude are f1=5 n / f2=9 n f3= 3 n and indicated angle 60 ْ during the displacement
What the net work done in the truck by the three forces
Does the kinetic energy the trunk in crease or decrease ?
