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 vis 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 O 50 N 05N O 5000 N

1 V:IV H.W.docx H.W: Two boxes are connected by a cord running over a pulley. The coefficient of kinetic friction between m, (5kg) and the table is 0.20. We ignore the mass of the cord and pulley and any friction in the pulley, which means we can assume that a force applied to one end of the cord will have the same magnitude at the other end. We wish to find the acceleration, a, of the system, which will have the same magnitude for both boxes assuming the cord doesn't stretch.
