The balcony on the first floor was sprinkled with water from the six floors next door, how could you

Using the kinetic energy theorem, 1 2mv 2=mgh, first measure the height of the first to sixth floors (you can measure one floor and then multiply by five). Suppose you live in a building with three households, and you live in a middle household, then there are the following situations:

1.The opponent is in the middle of the household, it can be known that the movement of the melon skin is in free fall, directly according to the above formula 2 of the opponent's east or west household, then the melon skin does a flat throwing motion, and there is a speed multiplied by the angle sine (the angle refers to the depression angle from the first floor to the sixth floor of the east or west household, which is very easy to measure) in the above formula.

However, I think the probability of coming out is 0 for the following reasons:

1. Difficulty in speed measurement.

2. Air resistance.

2. Wind speed 4 Gravitational acceleration (no deviation at all).

To sum up, this problem is difficult. Do not spray.

Investigate which of the six households has recently bought melons to eat, wouldn't you know?

The next time he throws it, you pretend to be hit and then shout. No one came out to see which one and there were probably people in the house, I said probably that one.
