The acceleration of high-speed aircraft is sometimes expressed in g’s (in multiples of the standard acceleration of gravity, whose value is 9.80 m/s^2). Determine the net force, in N, that a 90-kg man would experience in an aircraft whose acceleration is 6 g’s.

Sagot :

Answer:

The force is determine from the relation of forces that are acting on the man:

Fnet = Fup - Fg

ma = Fup - mg

6mg = Fup - mg

Fup = 7mg

=7•90•9.81 N

=6180.3 N

Fup = 6180.3 N
