1. The problem statement, all variables and given/known data A 1000,000 Kg aircraft drops a 1000 Kg packages of supplies over the surface of the earth. what approximate force felt by 100 Kg pilot at the instant of release. (a) 1N (b) 0.1N (c) 10N (d) zero 2. Relevant equations anything you can think of. 3. The attempt at a solution In starting aircraft is flying with constant speed. There is a constant downward force(mg) and a constant upward force by wings of plane applied. At the moment the package is dropped, Required force to maintain that height is decreased(since considerable mass decrease) but engines are still applying same amount of thrust so it will little move in upward direction. This extra force should equal to 1,000*9.8(weight of package). instantaneous acceleration of plane in upward direction is ~0.01. so upward force on the pilot will 100*0.01=1. That's what i think. Where am i wrong?
