1.4. CHAPTER 1, PROBLEM 4 5 1.4 Chapter 1, Problem 4 We are given that the weight in Old Russian units is W r = Mg r =(0 . 41 kg) g r =1lb r wherewedenotean Old Russian pound by lb r . We also know that, since mass is invariant, W USCS = Mg The conversion tables tell us that 1 slug = 14.594 kg. Hence, since g = 32.174 ft/sec
