Question

Chris P Nutts, who's mass is 80 kg, went skydiving. Right after jumping off the plane he is in free fall. What is the magnitude of the net force exerted on Chris P. Nutts? What is the direction of the net force exerted on Chris P. Nutts? What is the magnitude of his acceleration? What is the direction of his acceleration? After falling for a few seconds Chris P. Nutts has the speed of 90 m/s and acceleration of 6 m/s2 At this time is Chris P. Nutts in free fall? What is the magnitude of the net force now exerted on Chris P. Nutts? After falling for a while longer Chris P. Nutts deploys his parachute and eventually reaches terminal velocity of 5 m/s. At this time is Chris P. Nutts in free fall? What is the magnitude of the net force exerted on Chris P. Nutts? What is the magnitude of his acceleration?
