5. The highest waterfall in Canada is the Della Falls in British Columbia, with a change in elevation of 4.4 X 102 m. When the water has fallen 12% of its way to the bottom,
its speed is 33 m/s. Neglecting air resistance and fluid friction, determine the speed
of the water at the top of the waterfall.

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
