**Unformatted text preview: **by 2, and the acceleration due to gravity at the surface of Mercury need not be found. Substituting the given numbers, with y + upward, gives N. 10 . 16 ) s / m 80 .

Also note that although 2 a is known to two places, the sums in both numerator and denominator are known to three places....
