Question

Each second, 5525 m³ of water flows over the 670 m wide cliff of the Horseshoe Falls portion of Niagara Falls. The water is approximately 2 m deep as it reaches the cliff. What is its speed at that instant?

a) 8.24 m/s
b) 16.48 m/s
c) 32.96 m/s
d) 41.20 m/s

Answer 1

The speed of the water at the cliff is 8.24 m/s.

Step-by-step explanation:

To find the speed of the water at the cliff, we can use the equation:

Speed = Volume / Area

Given that the volume is 5525 m³/s and the area is 670 m, we can substitute these values into the formula:

Speed = 5525 m³/s / 670 m = 8.24 m/s

Therefore, the speed of the water at the cliff is 8.24 m/s.
