 Oct 13th 2017, 10:12 AM #1 Junior Member   Join Date: Oct 2017 Posts: 5 Physics- Direction & Magnitude During an episode of turbulence in an airplane you feel 190 N heavier than usual. If your mass is 78 kg, what are the magnitude and direction of the airplane's acceleration? For the F=ma, I manipulated the equation and have gotten, a=190N/78kg=2.4 or would the formula be W=ma, hence, 78kg/190N=0.410 is this correct? And how do I solve the other portion of the problem?

No

You can 190Newtons weight by 78 kilogrammes mass and get anything useful.

no ... check the free body diagrams for guidance in solving this problem. The Normal force is what a weight scale would read for each situation.
