Homework Help: Force given mass and acceleration problem

  1. Oct 24, 2012 #1
    1. The problem statement, all variables and given/known data
    Here is the problems exactly as written in the homework:

    A Ferrari accelerates from 0 to 100km/hr in 4.80 secs. What force (in Newtons) does a passenger with a mass of 68kg experience during the acceleration?

    2. Relevant equations
    a = v/t

    3. The attempt at a solution
    Ok...seems pretty straightforward, but the answer I come up with comes back as wrong. Can anyone point out my error?


    F=68*20.8 = 1416.4kg*km/hr = 1416.4N

    Nevermind. I see what I over looked. Forgot to convert km/hr to m/s.
