Angel Falls in southeastern Venezuela is the highest uninterrupted waterfall in the world, dropping 979 m (3212 ft). Assume that it takes 14 s for the water to fall from the lip of the falls to the river below. If the water lands 60 m from the base of the vertical cliff, what was its horizontal speed at the top?

• Physics -

in real life, air resistance is considerable, and cannot be ignored.

neglecting air resistance, then time to fall
h=1/2 g t^2 solve for time t.

velocity horizontal*time=60m solve for velocity.
