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

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
