The acceleration of high speed aircraft is sometimes express

The acceleration of high –speed aircraft is sometimes expressed in g’s (in multiples of the standard acceleration of gravity). Determine the net upward force, in N, that a 70-kg man would experience in an aircraft whose acceleration is 6g.

Solution

SOlution :

Here main thing is to balance the force

So

F-mg = ma

But a=6g is given

Hence

F= mg+6mg =7mg

F = 7*70*9.81 = 4806.9 N
