Homework Statement
Suppose the water at the top of Niagara Falls has a horizontal speed of 2.7 m/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 75° angle below the horizontal?
x direction
a = 0 m/s
v0x = 2.7 m/s
vfx= 2.7 m/s
x = ?
y direction
ay = -9.80 m/s2
v0y = 0 m/s
vfy = ?
y = ?
Other Info
Angle = 75 degrees below horizontal
t = ?
Homework Equations
Newton's laws of motion...but I'm not exactly sure which ones as it appears there are two variables missing from each one.
The Attempt at a Solution
I'm studying for my final this Friday. This question plagued me at the beginning of the term, I never got it. The class moved on, and so did I. But I'm looking at it again and am determined to get it, but am still drawing a blank.
I'd like to find t as that would help significantly, but each equation that I've considered with it has another unknown variable as well.
Kind of flustered...
