Homework Help: Force on a car passenger during acceleration.

  1. Feb 19, 2013 #1
    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 ???

    Welcome to PF Zsmitty3!

    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.
