The position of a point at time $t$ is given by $x = a + bt - ct^2$ and $y = at + bt^2$. The resultant acceleration of the point at time $t$ is given by:

  • A
    $2 \sqrt{b^2 + c^2} \text{ unit/s}^2$
  • B
    $2 \sqrt{c^2 + b^2} \text{ unit/s}^2$
  • C
    $2 \sqrt{c^2 + b^2} \text{ unit/s}^2$
  • D
    $2 \sqrt{c^2 + b^2} \text{ unit/s}^2$
