Suppose the water at the top of Niagara Falls has horizontal speed of 3.59m/s just before it cascades over the edge of the falls. At what vertical distance below the edge does the velocity vector of the water point downward at a 64.1 degree angel below the horizontal? From this information I got Ax=O Vox=3.59 Y=? Voy=? Ay=-9.80 So i need to figure otu Voy can i do 3.59sin (64)?? And then what formula do I need to use??
