Answer:
Approximately .
Assumption: the ball dropped with no initial velocity, and that the air resistance on this ball is negligible.
Explanation:
Assume the air resistance on the ball is negligible. Because of gravity, the ball should accelerate downwards at a constant near the surface of the earth.
For an object that is accelerating constantly,
,
where
- is the initial velocity of the object,
- is the final velocity of the object.
- is its acceleration, and
- is its displacement.
In this case, is the same as the change in the ball's height: . By assumption, this ball was dropped with no initial velocity. As a result, . Since the ball is accelerating due to gravity, .
.
In this case, would be the velocity of the ball just before it hits the ground. Solve for
.
.

Explanation because the distance covered is equal time intervals is the same or equal.
plzzz explain me your questions
Answer:
1.a storm with a violent wind, in particular a tropical cyclone in the Caribbean.
2.The Eye of a Hurricane. The eye is the region at the center of the hurricane, which is roughly circular in shape and usually has calm weather.
3.Hurricanes form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.
4.When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.
5.a rising of the sea as a result of atmospheric pressure changes and wind associated with a storm.
6.A hurricane dies down when it loses its energy source, which is usually warm water at the surface of the ocean.
7.Hurricane Katrina was so destructive because of a bunch of events that happened in just the right way. First, understand that Katrina was at one point a Category 5 storm and was predicted to hit New Orleans as a Category 4. It weakened to a Cat 3 and veered ever so slightly to the east, making the damage far less than it could have been.
