physics hortizontal and vertical
Angel Falls in southeastern Venezuela is the highest uninterrupted waterfall in the world, dropping 979 m (3212 ft). Ignoring air resistance, it would take 14 a for the water to fall from the lip of the falls to the river below. If the water lands 50 m from the base of the vertical cliff, what was its horizontal speed at the top?

$\displaystyle v_x = \frac{\Delta x}{\Delta t}$

Re: physics hortizontal and vertical
50m/14 sec
divide this right

3.5?
this is the vertical?

Which equation would be use to get the horizontal speed

Can someone help me figure this out?

You have already been told how to get it and have calculated the horizontal speed. The water has 0 vertical speed at the top and increases speed all the way down. But there is no horizontal component of force so the horizontal component of speed does not change: at constant speed, to go 50 m in 14 sec, makes the speed 50/14 m/sec.

Ok I redid it and it came out right
This is insane Physics to me, but I'm getting it a little. Online class is the worst.
