$A$ stone is thrown in a vertically upward direction with a velocity of $5 \, m s^{-1}$. If the acceleration of the stone during its motion is $10 \, m s^{-2}$ in the downward direction,what will be the height attained by the stone and how much time will it take to reach there?

  • A
    $t=1 \, s; s=1.25 \, m$
  • B
    $t=0.5 \, s; s=2.25 \, m$
  • C
    $t=1 \, s; s=2.5 \, m$
  • D
    $t=0.5 \, s; s=1.25 \, m$
