8. In order to drag a 100 kg log along the ground at uniform velocity you have to pull on it with a force F = 300 N î. What is the resistive force exerted by the ground on the log? In the absence of air drag, the acceleration due to gravity is 9.81 m/s². What is the magnitude of the drag force of the air on a body of mass 0.25 kg falling freely with a downward acceleration of 9.20 m/s?. 9. 10. A parachutist relies on air resistance to decrease her downward velocity. She and her parachute have a mass of 55.0 kg, and air resistance exerts a total upward force of 600 N on her and her parachute. What is the acceleration of the parachutist?
