Explanation / Answer

PartA) rx = 3 + integral vdt

    = 3 - 3t^2 /2

   = 3 - 3*12^2 /2

    = - 213 m

Partb) ry = 2 + integral vdt

        = 2 +2t^3 /3

        = 2 + 2*12^3 /3

         = 1154 m

PartC) ax = dv/dt

            = - 3 m/s^2

PartD) ay = dv/dt

         = 4t

        = 4*12

      = 48 m/s^2
