$A$ 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$t=0.5 \, s; s=1.25 \, m$
