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?
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.
