The height of the upper falls at yellowstone falls is 33 m. when the water reaches the bottom of the falls, its speed is 26 m/s. neglecting air resistance, what is the speed of the water at the top of the falls?

Speed of water at the top of fall = 5.40 m/s

Explanation:

We have equation of motion

Here final velocity, v = 26 m/s

a = acceleration due to gravity

displacement, s = 33 m

Substituting

Speed of water at the top of fall = 5.40 m/s
