blackboard.albany.edu A QUESTION 5 A falling body on Earth will generally not fall at constant acceleration in reality, due to air resistance (or drag). The equation for the drag force Fd is Fd = 0.5 (Cd A) pv2 where Cd is the unitless drag coefficient of a body (which depends on the body's density and other properties), A is its cross-sectional area as it falls, p is the density of the air, and v is the body's velocity with respect to the atmosphere. Now, you may need to look up a couple of things to get a reasonable answer here, but anyway: The drag force on a person falling belly-first (as shown) at a speed of 30.0 m/s through the atmosphere is approximately O 500 N О 50 N O 5 N О 5000 N QUESTION 6 Save All Click Save and Submit to save and submit.
