    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?

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

    50m/14 sec
    divide this right

    3.5?
    this is the vertical?

    Which equation would be use to get the horizontal speed

    Re: physics hortizontal and vertical

    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.

    This is insane Physics to me, but I'm getting it a little. Online class is the worst.
