(14.2) A block of mass m = 10 kg riding on a frictionless horizontal plane is subjected to five forces. The weight of the block and the normal force of contact with the plane both act in the vertical direction, cancel, and may be henceforth ignored. Three applied forces, →F1 , →F2 , →F3 , act horizontally on the block. The information that we have been able to gather about the applied forces is summarised as follows: F1 = 10...
