Force on a car passenger during acceleration.

[Zsmitty3]

1. A Car accelerates from 0-100 km/h (27.77 m/s) in 4.8s. What F (in Newtons) does a passenger of mass 68 kg experience during acceleration



2. I feel like I'm solving this too easily and am missing something



3. F=ma. a= Δv/ΔT.
27.77/4.8= 5.78
F= 68*5.78
F=393.52N ?

I haven't checked your arithmetic, but your method is entirely correct. The problem is not difficult conceptually. It's just a straight application of Newton's second law.
