Jason places his economics book (3 kg) on a level table. He then puts his calculus book (5 kg) on top of the economics book, then puts his physics book (2 kg) on top of the calculus book. Find: (a) the force that the table applies to the economics book (b) the force that the economics book applies to the calc book (c) the force that the calc book applies to the physics book Any help is greatly appreciated
