A river flows toward the east. Because of your knowledge of physics, you head your boat 44° west of north and have a velocity of 8.0 m/s due north relative to the shore. (a) What is the velocity of the current?
The falls are approximately 108 m high. If the river is flowing horizontally at 3.60 m/s just before going over the falls, what is the speed of the water when it hits the bottom? Assume the water is in freefall as it drops.
