**bobpursley**, Sunday, March 7, 2010 at 9:22pm102=vi(6)+1/2 a 36

18=vi(2)+ 1/2 a 4

multiply the second equation by 3, then subtract the second equation from the first.

**Damon**, Sunday, March 7, 2010 at 9:24pmd = Vi t + (1/2) a t^2

18 = Vi (2) + (1/2) a (4)

102 = Vi (6) + (1/2) a (36)

18 = 2 Vi + 2 a

or

9 = Vi + a

102 = 6 Vi + 18 a

or

17 = Vi + 3 a

8 = 2 a

a = 4 m/s^2

and

Vi = 5 m/s
