Asked by Chris
Can I get help with these questions?
The beautiful Multnomah Falls in Oregon are approximately 206m high. If the Columbia river is flowing horizontally at 2.90m/s just before going over the falls, what is the overall velocity of the water when it hits the bottom?

figure the time to fall 206m: 4.9t^2 = 206
The vertical speed v = 9.8t
so the final speed is √(v^2+2.9^2)
The vertical speed v = 9.8t
so the final speed is √(v^2+2.9^2)
