An airplane has a mass of 29000 kg and takes off under the influence of a constant net force of 42500 N. What is the net force that acts on the plane's 72-kg pilot?

Nice question.. Pretty Tricky.. it was value jet, the plane would just crash in the everglades.. but since it apparently isn't.....

For the plane:
Take the F_net = m*a     (newton rocks)
42500N = 29000kg * a
Solve for a...
a = 1.4655........
This means the plane is only accelerating at 1.47 m/s^2

For the Pilot, he feels this..
But since he is much lighter, he amount of force it take him to accelerate at that same speed is:
F_net = 72kg*1.47 = 105.51...... Netwons
