3) A soccer ball has just been kicked off the edge of the Grand Canyon which has a height of 2,400 meters above the Colorado River at its base. Ignoring air resistance, what is the
velocity of the ball halfway down (1200 meters above the river)? And, what is the
velocity of the ball when it hits the water (when h=0 meters)?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
