Suppose the water at the top of Niagara Falls has a horizontal
speed of 3.78 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 60.5 ° angle below the
horizontal?
Homework Answers
Answer #1
Use equation of kinematics in vertical and horizontal direction
separately to find the required distance below the edge as shown
below. Initially at the edge, the vertical initial speed is
zero.
