Question

"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 s 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 verti-cal cliff, what was its horizontal speed at the top"

Answer:

The value  is $v = 3.57 \ m/s$

Explanation:

From the question we are told that

  The depth  is  $d = 979 \ m$

   The time taken for water to fall to below the river is  $t = 14 \ s$

   The  horizontal distance from the base of the vertical cliff is  $h = 50 \ m$

     Generally  the horizontal speed at the top is mathematically represented as

         $v = \frac{h}{t}$

=>      $v = \frac{ 50}{ 14 }$

=>     $v = 3.57 \ m/s$
