A stone is projected vertically upwards with a speed of $5.0\,\text{m s}^{-1}$. By the time the stone reaches its greatest height, all the energy originally in its kinetic store has been transferred to its gravitational potential store. Which equation gives the greatest height $h$ reached by the stone?
- A$h = \dfrac{9.8}{2 \times 5.0^2}$
- B$h = \dfrac{5.0^2 \times 2}{9.8}$
- C$h = \dfrac{5.0^2}{2 \times 9.8}$
- D$h = \dfrac{2 \times 9.8}{5.0^2}$
