a typical meteorite’s weight, surface area, and coefficient of drag

a typical meteorite’s weight, surface area, and coefficient of drag; air density close to Earth

Answer 1

To calculate the terminal velocity of a typical meteorite just before it hits Earth, Hanna needs to find:

a typical meteorite’s weight, surface area, and coefficient of drag; air density close to Earth

This option includes all the necessary components for calculating terminal velocity, which are: the weight (or mass), the surface area, the coefficient of drag (which relates to how the meteorite interacts with the air), and the air density (which affects the drag force experienced by the meteorite as it falls).
