$A$ force $\vec{F} = a \hat{i} + b \hat{j} + c \hat{k}$ is acting on a body of mass $m$. The body was initially at rest at the origin. The coordinates of the body after time $t$ will be:

  • A
    $\frac{at^2}{2m}, \frac{bt^2}{2m}, \frac{ct^2}{2m}$
  • B
    $\frac{at^2}{2m}, \frac{bt^2}{m}, \frac{ct^2}{2m}$
  • C
    $\frac{at^2}{m}, \frac{bt^2}{2m}, \frac{ct^2}{2m}$
  • D
    $\frac{at^2}{2m}, \frac{bt^2}{2m}, \frac{ct^2}{m}$
