7. A stone is thrown horizontally at \( 15 \mathrm{~m} / \mathrm{s} \) from the top of a cliff. It takes \( 5 \mathrm{~s} \) to reach the ground. a) How far from the base of the cliff does the stone land? b) How fast is it moving just before it strikes the ground?

A hiker stands on the edge of a cliff $490 \mathrm{~m}$ above the ground and throws a stone horizontally with a speed of $15 \mathrm{~m} \mathrm{~s}^{-1} .$ The time taken by the stone to reach the ground is (a) $5 \mathrm{~s}$ (b) $10 \mathrm{~s}$ (c) $12 \mathrm{~s}$ (d) $15 \mathrm{~s}$
A stone is thrown vertically upward with a speed of 12.5 $\mathrm{m} / \mathrm{s}$ from the edge of a cliff 75.0 $\mathrm{m}$ high $($ Fig. 49$) .$ (a) How much later does it reach the bottom of the cliff? $(b)$ What is its speed just before hitting? (c) What total distance did it travel?
