Approximating Answers When Exact Numbers Are Involved

[QUOTE="TRB8985, post: 6837496, member: 355135"] Thank you both for your replies! I understand what you mean. I guess the confusion here arises since, in every problem throughout this book up to this point, our solution manual uses the generic two-figure 9.8 m/s² quantity for [I]g[/I]. It just seemed really weird that, now all the sudden, 9.80 m/s² is used without any forewarning anywhere and no explanation. Does this mean we are allowed to introduce an extra significant figure in [I]g[/I] in these kinds of situations? It doesn't seem very consistent, and I don't want to invent additional accuracy when I shouldn't be. Hopefully that makes sense! [/QUOTE]
