hannah wants to calculate the terminal velocity of a typical metorite just beofre it hits the earth she researches meteorites at the library on the internet what information does she need to find
a typical metrories surface area and coeefciant of drag air density close to earth
a typical meterorites mass and average velocity
a typical meterorites weight surface area and cofficient of drag air density close to earth
a typical weigth surface and coffcient of drag
a typical meterorites mass and weight surface area and coefficient of drag air density close to earth.
To calculate the terminal velocity of a typical meteorite just before it hits the Earth, Hannah would need to find the following information:
1. Surface Area: Hannah needs to know the surface area of the meteorite in square meters. This information is necessary because the surface area affects how much air resistance the meteorite experiences as it falls.
2. Coefficient of Drag: Hannah must find the coefficient of drag for the meteorite. The coefficient of drag is a dimensionless value that represents the object's shape and surface roughness. It determines how much resistance the object experiences due to air friction.
3. Air Density: Hannah needs to find the air density close to the Earth's surface. Air density is a measure of how many air particles are present in a given volume. As air density increases, the amount of air resistance experienced by the meteorite also increases.
4. Mass: Hannah should find the mass of a typical meteorite. The mass is the amount of matter contained within the object and is usually measured in kilograms.
5. Average Velocity: Hannah needs to determine the average velocity of the meteorite. This velocity represents the average speed at which the meteorite is falling towards the Earth.
By gathering and plugging in these pieces of information into the appropriate equations, Hannah can calculate the terminal velocity, which is the maximum velocity a falling object like a meteorite can reach due to the balance between gravitational force and air resistance.
To calculate the terminal velocity of a typical meteorite just before it hits the Earth, Hannah needs to find the following information:
1. Meteorite's surface area: This can be determined by researching the average dimensions or shape of the meteorite. The surface area will affect the drag force acting on the meteorite during its descent.
2. Coefficient of drag: The coefficient of drag is a factor that represents the resistance the meteorite will experience from the air. It depends on the shape and surface characteristics of the meteorite. Hannah can search for typical values or ranges of coefficient of drag for meteorites.
3. Air density close to Earth: The density of air will influence the amount of resistance the meteorite encounters. Hannah can look for the average air density at the altitude where meteorites typically enter Earth's atmosphere.
It's important to note that Hannah does not need to find the mass, weight, or average velocity of the meteorite to calculate its terminal velocity.
