Answer:

the diver's speed is independent of the launch height.

Explanation:

For this exercise we must use Newton's second law

              fr - W = m a

the friction force has the general form

              fr = b v

Let's analyze this equation to find out what happens with the speed of the distant club.

When jumping, the initial speed is zero, so the friction force is zero and has an acceleration equal to the acceleration of gravity, as the speed increases the friction force increases decreasing the acceleration until it becomes zero, when it arrives at this value the velocity it has is called terminal velocity and this velocity remains fixed in relation to the trajectory.

             fr = W

             v = cte

The distance or time in which this equilibrium is reached is relatively fast, so the diver's speed is independent of the launch height.

Which part of the atmosphere is the highest layer in which planes can fly?
Rudiy27

Answer:

the stratosphere

Explanation:

Planes most commonly fly in the lower stratosphere to avoid turbulence which is common in the troposphere. little to no clouds appear in the stratosphere due to low humidity so it is easier to see.

ankoles [38]

Drag;

Drag is the aerodynamic force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane (even the engines!). How is drag generated? Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas).

The drag on an object depends on several variables. The most important of them, to understand the experiments you carried out is the area of the object.

The area of the object is the most important factor to understand the experiments.
