Question

gravity and air resistance quick check
hanna wants to calculate the terminal velocity of a typical meteorite just before it hits earth. she researches meteorites at the library and on the internet. what information does she need to find? (1 point)
o a typical meteorites surface area and coefficient of drag; air density close to earth
o a typical meteorites weight, surface area, and coefficient of drag; air density close to earth
o a typical meteorites mass and average velocity
o a typical meteorites weight, surface area, and coefficient of drag

Explanation:

Terminal velocity formula is \(v_{t}=\sqrt{\frac{2mg}{
ho AC_{d}}}\), where \(m\) is mass (related to weight \(mg\)), \(
ho\) is air density, \(A\) is surface area, and \(C_{d}\) is coefficient of drag. So need meteorite's weight (or mass), surface area, coefficient of drag and air density.

Answer:

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