**Reiny**, Tuesday, October 19, 2010 at 11:48pma) find s(3) - s(0)

b) avg vel in first 3 sec = (s(3) - s(0))/3

c) find derivative of s(t), then sub in t = 3

d) find derivative of c) result, sub in t=3

e) mmmh, one of those derivatives (velocity or acceleration ) must be zero when I change direction ...
