The falls are aproximately 108m high. if the river is the flowing horizontally at 3.60m/s just before going over the falls, what is the speed of the water when it hits the bottom? Assume the water is in free fall as it drops

the answer is to check all of them! they all apply well at least i think so!

this could be newton#'s law of cooling. the cooling curve is exponential

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
