**drwls**, Monday, November 3, 2008 at 2:21amThe acceleration is

dv/dt = 32t i + 12 t^2 j + 5 k

Plug in t = 2 to get the acceleration vector at t =2.

The position vector is the integral of v(t),

r(t) = [(16/3)t^3 + a]i +

(t^4 + b)j + [(5/2)t^2 + 2t + c] k

where a, b and c are constants of integration. Use the position at t = 0 to solve for them. It appears that a=b=c=0
