Problem

A rock is thrown from ground level at a speed of

12\,\text{m}\!\cdot\!\text{s}^{-1}

at a

45^{\circ}

angle. Compare its horizontal range on the Moon (

g \approx 1.6\,\text{m}\!\cdot\!\text{s}^{-2}

) with its range on Earth (

g \approx 9.8\,\text{m}\!\cdot\!\text{s}^{-2}

). State whether the Moon range is greater, equal, or less, and give a brief explanation.
