6. Numbers are substituted, with their units, for the input symbolsand the units are then reduced to obtain the units of the answer:
d =1
2(32ft/s2)(2.1 s)2 = 70.56ft 71ft
7. Numerical answers are given to an appropriate number of digits,neither more nor less. A number like 130 must finally be written soas to show its number of significant digits (1.3 102 or 1.30 102
or . . . ). If only multiplications and divisions are used to computethe answer, then the final answer should have exactly the numberof digits of the least precise of the input parameters (see the exam-ples in #6 above and #10 below). If subtraction is involved, thesubtraction must be checked to see if some precision is thereby lostdue to cancellation of the leading digits.
8. The situation is sketched, showing themeaning of the symbols used:
r
P
q
x
y
9. Assumptions used at the beginning of a problem are clearly statedin both words and equations:
1. I combine Coulombs Law: F = keq q
r2r
and Newtons Second Law: F = mato get . . .
10. Equality signs that are part of a derivation sequence, but whichbegin different lines on the page, lie directly underneath each other:
